The slope intercept form calculator helps you to find the equation of a line from given two points, one point & slope, and slope & intercept of a line. In the simplest term, this slope intercept calculator will determine the x and y-intercept as well as the slope of a line by using slope intercept equation.
Also, consider this simple slope calculator that finds a slope of a line passing through the two given points in the Cartesian coordinate plane.
The slope intercept equation is mentioned below and an online lope intercept form equation calculator also uses the same equation to provides you the precise calculations for slope-intercept form.
y = mx+c
Slope-intercept form examples:
These all equations are in the slope-intercept form.
These equations are not in the slope-intercept form.
Also, this simple, but accurate point slope calculator helps to determine the equation of a line “y – y1 = m(x – x1)” by using the coordinate points and slope of the line.
The great advantage of slope-intercept form is that it gives the two main features of a line.
A line y=2x+1 having slope 2 and intercept c is 1.
This form gives the slope and y-intercept form of the line, that’s why it is called the slope-intercept form. Our slope intercept form calculator minimizes your worry by giving both coefficients of a line that are slope and y-intercept.
As we know, the value of the x coordinate at y-axis is zero. So, if we have to find the y-intercept of the line then, we should substitute x=0 in the linear equation.
Substitute x=0 in this equation.
8y=9(0) + 13
This online y intercept finder displays the y-intercept of the line accurately so that you can come to know at which point the line intersects the y-axis.
As we know about slope “ratio of the change in y to the change in x coordinates between any points of the line”:
m = change in y/change in x
m = Δy/Δx
m = rise/run
If a change in x is only one (1) unit, then the change in y equals the slope of the line,
m = change in y/1
m = change in y
Now, look at how much increases in y value by changing x values.
|0||1+0×4 = 1|
|1||1+1×4 = 1+4|
|2||1+2×4 = 1+4+4|
|3||1+3×4 = 1+4+4+4|
|4||1+4×4 = 1+4+4+4+4|
|5||1+5×4 = 1+4+4+4+4+4|
We see that every time when x increases 1 unit, y increases 4 units. So, the slope of a line y=4x+9 is 4. Also, you can use slope and y intercept calculator that helps to find the slope-intercept form from the given slope (m) and y-intercept (c).
The value at which the straight line intersects the x-axis (horizontal axis). You can calculate the x-intercept in the following way:
Find the x-intercept of 9y=3x+7?
You can find x-intercept of the given equation by using a basic slope intercept formula.
Substitute y=0 in the given equation (problem):
Our x and y intercept calculator helps you to find out the x and y-intercepts of a line for you.
It is helpful in many fields like in science linear models can be described in slope intercept form. In Statistics, the regression line can be found with the help of slope intercept form. Let’s solve a real-world problem with the slope-intercept form.
A boy is eating a 13.9cm long ice cream cone. It starts melting at a rate of 3cm/minute. If the boy didn’t eat the ice cream, how much left ice cream after 4 minutes?
First of all,
Slope is -3 because ice cream is decreasing.
Y-intercept is 13.9 and x intercept is 4miutes.
Then, put the values in slope intercept form.
y= (-3) (4) +13.9
So, after 4minutes ice cream measures only 1.9cm.
It is difficult and tricky to do the complex calculations by hand; you can simply use above slope intercept form calculator..
The x and y intercepts of the line can be helpful in many of the real world problems. Consider a situation when a bike is moving towards you, its movement plotted in distance-time graph. The x-axis represents the time and y-axis represents the distance covered by the bike. Then, you can easily find out the time or distance at any point in the graph with the help of x&y intercepts.
We can differentiate the following three groups of linear equation:
The first two can be determined by this slope-intercept form calculator but the last type is not determined by the slope-intercept calculator. The last method is very tricky and to understand this type we need to know about the asymptotes.
It is the line to which the function or curve comes closer or closer but never crosses or touches the line. Let’s talk about an example to clear the concept about asymptotes.
If we have an equation y=6/x and want to find the y intercept by substituting the value of x with 0, then we get the undefined answer.
The value of y increases very rapidly if we take the value closer to 0.In this scenario, a linear equation x=0 is the asymptote of the function y=6/x.
As the slope intercept form is y=mx+c , the slope is m and y-intercept is c. Therefore the slope of y=7x+2 is 7 and y-intercept is (0, 2).
For the graph of line, we need two points one point we already have is (0, 2).As the slope of line is 7 so, the other point is (0+1, 2+7) = (1, 9).
Now, the graph off this equation is as follow:

The output of the each option is different, the slope-intercept calculator display the results according to the selected option.
Moreover, if you want to convert a standard form to slope form, you can use our free online standard form to slope intercept form calculator too.
To find the slope intercept form from the given two points, just follow the given steps for manual calculation.
Let’s have an example to clarify the concept:
Find the slope intercept form of the points (2, -1) & (5, 3)?
Calculate the slope from two points with formula:
m = y2 – y1 /x2 – x1
y2 = 3
y1 = -1
x2 = 5
x1 = 2
m = 3 + 1 /5 – 2
m = 4 /3
m = 1.333
Find out the y-intercept by entering the values of slope, y and x in equation.
3 = (1.333) (5) +c
3 = 6.665+c
c = 3-6.665
c = -3.665
Now enter the values of slope and y-intercept to get the slope-intercept form.
y = 1.333x-3.665
To find the slope intercept form from the given intercept (c) & slope (m), just enter the values in the equation. Have a look at example:
Find out the slope-intercept form having slope -8 & y-intercept is 13?
The equation is,
y = mx + c
y = (-8) x + 13
y = -8x + 13
Our free online calculator enables you to find the slope-intercept form equation from intercept (c) & slope (m) accurately.
You can write an equation for the line with slope and intercept given by using the formula:
y = mx + c
Here, m is 6 & c is -3.So,
y = 6x + -3
As we know, there are two types of intercept, x & y-intercept. If the graph cuts the x-axis with coordinates (x, 0), then we say it is x-intercept. If the graph cuts the y-axis with coordinates (0,y) , then we say it is y-intercept. To find the x & y-intercept using a graph, just see where the line cuts the x & y-axis respectively.
You can find the equation of line with one point and slope with the formula:
y + 4 = 4 (x+2)
y + 4 = 4x+8
y = 4x+8-4
y = 4x+4
With these two points (0, 5) & (-5, 0), you can find the slope by the following formula.
m = 0 – 5 /-5 – 0
m = -5 /-5
m = 1
To find the y-intercept, put x=0 in the equation:
=2(0-1) ^2 + 5
=2(-1) ^2 + 5
= (-2) ^2 + 5
=4 + 5
Yes, the formula y = mx + b can be reversed to solve for x. It is possible if we subtract b from both sides and divide by m on both sides,
y – b = mx + b – b
y – b = mx
(y – b)/m = mx/m
(y – b)/m = x
Using the two point method use above in the article, one point is (3,-12) & other is (1, 0). Find the slope of a line with the formula m = y2 – y1 /x2 – x1 line then, solve for the slope intercept form as y = mx+c.
After this substitute x=0 in the equation to find the y-intercept.
You can’t find the y-intercept with just slope given; you have to be given more information than the slope of a line.
If the slope of a line is undefined means it is infinite, then the line is parallel to y-axis (vertical line).
To find the x-intercept of the equation, set all the other variable set to zero.
2x – y = 8
2x – 0 = 8
2x = 8
2x/2 = 8/2
x = 4
The slope intercept form is very helpful in solving the real world problems, distance between the two points and slope of a line. Students use the slope-intercept form to better understand the different equations of line and how to determine the general equation of line. So, students and professional can use this online slope intercept form calculator to calculate the slope intercept form in a fraction of seconds.
