Gradient – Rise over run

To calculate the gradient of any line select any 2 points on the line and find the rise and run.

Because:

`Gradient=(Rise)/(Run)`    (Gradient is Rise over Run)

It's grey (gradient) and then the sun rises overhead (rise over) as we go for a run (run).

You can run in either direction.

 

Example

Find the gradient of the graph below:

`Rise=3-1=2`

`Run=4-1=3`

Therefore `Gradient=(Rise)/(Run)`

`Gradient=2/3=0.66`
