Question

What is the slope of the line between `(-2,2)` and `(-1,87)`?

Answer 1

slope = 85

Explanation:

To find the gradient (slope) of a line passing through 2 points use the `color(blue)" gradient formula "`

`m = (y_2 - y_1)/(x_2 - x_1)`

where `(x_1,y_1)" and " (x_2,y_2)" are 2 coordinate points "`

let `(x_1,y_1)=(-2,2)" and " (x_2,y_2)=(-1,87)`

now substitute these values into the formula.

`rArr m = (87-2)/(-1-(-2)) = 85/1 = 85`
