Two point form calculator is an online tool that finds the equation of a line if two points are given. It calculates the point slope form equation by using 2 points of a straight line.

Equation of a straight line can also be evaluated with one point and slope using our point slope form calculator.

## Two point slope form equation

The formula to find equation of straight line with two points is:

Where,

x1, x2 are points on x-axis,

y1, y2 are points on y-axis.

## Finding equation of a straight line with 2 points

Below, you can find the example of a line passing through two points.

Example:

Find the equation of line if it is passing through (4, 2) and (6, -5).

Solution:

Step 1: Write down the point slope form equation of two points.

Step 2: Substitute the values in the equation.

Cross multiply the above equation.

2(y - 2) = -7(x - 4)

2y – 4 = -7x + 28

7x + 2y = 32

To get the slope intercept of a line, use our slope intercept form calculator.
