slope = 85

Explanation:

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

m = (y_2 - y_1)/(x_2 - x_1) m=y2−y1x2−x1

where (x_1,y_1)" and " (x_2,y_2)" are 2 coordinate points "(x1,y1) and (x2,y2) are 2 coordinate points

let (x_1,y_1)=(-2,2)" and " (x_2,y_2)=(-1,87) (x1,y1)=(−2,2) and (x2,y2)=(−1,87)

now substitute these values into the formula.

rArr m = (87-2)/(-1-(-2)) = 85/1 = 85 ⇒m=87−2−1−(−2)=851=85
