The slope intercept form calculator finds the equation of the straight line based on the given two points, one point, or the intercept & slope data.  With it, you can also find the slope and y-intercept of any linear equation, enhancing precision and bringing clarity in your mathematical calculations.

What Is Slope Intercept Form?

The slope intercept form of the linear equation is y = mx + c that is constructed with y-intercept and slope of the line “m”. This form of the linear equations is known as the slope intercept form. The slope signifies the degree of incline or steepness of a line.

Slope Intercept Formula:

The formula that is used to find the slope intercept form equation is outlined below:

 y = mx+c


  • m = Slope of line 
  • x = x- coordinate of the line 
  • y = y-coordinate of the line 
  • c = y-intercept of the line 

The “m”  is the change in y and along with the x coordinates at any point of intersection of “x” and “y” You can also find the x-intercept of a line with the help of the above formula. The x-intercept is the value of the x at which the line crosses the x-axis.

How To Find The Slope Intercept Form (Equation of A Straight Line)?

Follow the below mentioned example to find the equation of slope intercept:

Practical Example:

Find the slope intercept form of the line with a slope is “2” and the y-intercept “5”. Solution:

Step 1:

Slope of the line = m =  2 y-intercept = c = 5

Step 2:

The slope intercept form of linear equations is: 

y = mx+c

m = 2 and c = 5

⇒ y  = 2x +5

By putting the given values in slope intercept formula you will get the slope intercept form equation in which y = 2x + 5. Graph of y = 2x + 5 Slope Intercept Form Grpah Also, consider this simple slope calculator that finds the slope of a line passing through the two given points. Keep in mind that all equations are not the same, some formulas describe curves that may never intercept the y-axis, the x-axis, or both of them.

Examples of Slope-Intercept Form:

In the following table, we have provided some examples so that you can easily understand how you can write the linear equations in slope intercept form.

Is Slope Intercept Form The Same As Standard Form?

No, because they are two different ways of defining a straight line. 
  • Slope intercept form equation = y = mx +b
  • Standard form =  Ax + By + C = 0

How Do You Find The Slope Between Two Points?

To find the equation of a line having two points, follow the below-mentioned steps:
  • Determine the slope using the following formula, m = (y₂ - y₁) / (x₂ - x₁)
  • After that use the point-slope to get the equation of the straight line as below:
  • y - y₁ = m(x₂ - x₁).
