m = 4

Explanation:

To find slope use the# color(blue)(" gradient formula")#

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

where (# x_1 , y_1) ,(x_2 , y_2 )color(black)( " are 2 points ")#

for this question let

#( x_1 , y_1 ) = (- 4 , - 8 ) color(black)(" and ") (x_2 , Y_2) = (-2,0)#

substitute values into formula :

# m =( 0 -(-8))/(-2-(-4)) = 8/2 = 4#
