- 11/5 −115

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) = (2,9)" and " (x_2,y_2) = (7,-2)(x1,y1)=(2,9) and (x2,y2)=(7,−2)

then m = (-2 - 9 )/(7 - 2 ) = -11/5 m=−2−97−2=−115
