Slope of line through #(x_1,y_1)=(-4,-8)# and #(x_2,y_2)=(-2,0)#is
#color(white)("XXXX")#4

Explanation:

The slope between #(x_1,y_1)# and #(x_2,y_2)# is given by the formula:
#color(white)("XXXX")##m = (y_2-y_1)/(x_2-x_1)#

For the given data points:
#color(white)("XXXX")##m= (0-(-8))/(-2-(-4)) = 8/2 = 4#
