Point Slope Form Calculator

The point slope form calculator helps you to calculate point slope form of a line equation by using line’s slope and point on it. Get step by step calculations and graph of the equation to check the position of the point slope form coordinates on a 2D plane.

What is Point Slope Form Formula (Equation)?

The point slope form equation is given as,

$$ y-y1=m (x-x1) $$

Here, \(y1\) and \(x1\) are the coordinate points in the cartesian coordinate plane.

And \((m)\) represents the slope of the line. Our point slope equation calculator also performs calculations according to this formula.

What is an Equation of a straight line?

The equation of any straight line called the linear equation and it is written as,

$$ y=mx+b $$

Here,

\(m\) is the slope of the line.

\(b\) is the \(y-intercept\) of the line. It is the point where a line crosses the \(y-axis\).

How to solve point slope form manually (step-by-step)?

This formula used to find out the point slope form is as follows,

$$ y-y1= m (x-x1) $$

Apart from this formula, you can use point slope form calculator to perform instant calculations.

For example:

The slope of a line is given as 7 and the point is (2,5). Find out the slope point form?

Solution:

Here the \(x coordinate\) is 2 and \(y coordinate\) is 5, slope is 7.

$$ x1=2 $$

$$ y1=5 $$

$$ m=7 $$

By putting the values in the point slope equation,

$$ y-5 = 7(x-2) $$

$$ y-5 = 7x-14 $$

$$ y = 7x-14+5 $$

$$ y = 7x-9 $$

$$ 7x-y-9 = 0 $$

This point slope formula solver does calculations according to this formula.
