Enter the original slope (Y/X) into the Inverse Slope Calculator. The calculator will evaluate and display the Inverse Slope. 

Inverse Slope Formula

The following formula is used to calculate the Inverse Slope. 

IS = 1 / OS
  • Where IS is the Inverse Slope ((X/Y))
  • OS is the original slope (Y/X) 

To calculate the inverse slope, divide 1 by the original slope.

How to Calculate Inverse Slope?

The following example problems outline how to calculate Inverse Slope.

Example Problem #1:

  1. First, determine the original slope (Y/X).
    • The original slope (Y/X) is given as: 5/6.
  2. Finally, calculate the Inverse Slope using the equation above: 

IS = 1 / OS

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

IS = 1 / OS = 6/5

Example Problem #2: 

For this problem, the variables needed are provided below:

original slope (Y/X) = 7/10

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

IS = 1 / OS = ?
