Enter the coordinates of point 1 and the coordinates of point 2 into the Two Point Slope Calculator. The calculator will evaluate and display the Two Point Slope. 

Two Point Slope Formula

The following formula is used to calculate the Two Point Slope. 

TPS  = (Y2-Y1) / (X2-X1)

  • Where TPS is the Two Point Slope (y/x)
  • X1,Y1 is the coordinates of point 1 
  • X2,Y2 is the coordinates of point 2 

How to Calculate Two Point Slope?

The following example problems outline how to calculate Two Point Slope.

Example Problem #1:

  1. First, determine the coordinates of point 1. 
    • The coordinates of point 1 is given as: (4,5).
  2. Next, determine the coordinates of point 2. 
    • The coordinates of point 2 is provided as: (10,12).
  3. Finally, calculate the Two Point Slope using the equation above: 

TPS  = (Y2-Y1) / (X2-X1)

The values given above are inserted into the equation below and the solution is calculated:

TPS  = (12-5) / (10-4) = 7/6 (y/x)


Example Problem #2: 

For this problem, the variables needed are provided below:

coordinates of point 1 = (6,6)

coordinates of point 2 = (14,20)

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
