# What is the formula to calculate slope?

### 2 Answers | Add Yours

when you were given a graph, you can use

slope = rise/run or change in y/change in x

and when you were given by 2 points you can use the 3rd formula.

:)

slope= rise/run

slope= change in y/change in x

slope=(y2-y1)/(x2-x1)

Hope this helps.
