m = 4

Explanation:

To find slope 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) ,(x_2 , y_2 )color(black)( " are 2 points ")x1,y1),(x2,y2) are 2 points

for this question let

( x_1 , y_1 ) = (- 4 , - 8 ) color(black)(" and ") (x_2 , Y_2) = (-2,0)(x1,y1)=(−4,−8) and (x2,Y2)=(−2,0)

substitute values into formula :

m =( 0 -(-8))/(-2-(-4)) = 8/2 = 4m=0−(−8)−2−(−4)=82=4
