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

## How to Calculate Average Slope?

The following example problems outline how to calculate Average Slope.

Example Problem #1:

- First, determine the initial slope.
- The initial slope is given as: 1.5.

- Next, determine the final slope.
- The final slope is provided as: 2.5.

- 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** = ?**
