Enter the initial slope and the final slope into the Average Slope Calculator. The calculator will evaluate and display the Average Slope. 

Average Slope Formula

The following formula is used to calculate the Average Slope. 

AS = (IS + FS) / 2
  • Where AS is the Average Slope (Y/X)
  • IS is the initial slope 
  • FS is the final slope 

To calculate an average slope, add together the initial and final slope, then divide by 2.

How to Calculate Average Slope?

The following example problems outline how to calculate Average Slope.

Example Problem #1:

  1. First, determine the initial slope.
    • The initial slope is given as: 1.5.
  2. Next, determine the final slope.
    • The final slope is provided as: 2.5.
  3. Finally, calculate the Average Slope using the equation above: 

AS = (IS + FS) / 2

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

AS = (1.5 + 2.5) / 2 = 2 (Y/X)

Example Problem #2: 

For this problem, the variables needed are provided below:

initial slope = 6

final slope = 8

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

AS = (IS + FS) / 2 = ?
