Question

What is the slope of the line passing through the following points: `(-2,-1) , (5, 1)`?

Answer 1

`m = 2/7`

Explanation:

Slope is defined as `"the change in y"/"the change in x"`

The formula to find this is: `m = (y_2 - y_1)/(x_2 -x_1)`

`m = (1- (-1))/(5- (-2)) = 2/7`

If we had subtracted the other way round we would have ended up with
`m =(-2)/(-7)" but this also simplifies to " 2/7`
