The slope of the line through #(−9 , 6 )# and #(−6 , −9 )# is #-5#.

Explanation:

The formula for the slope of a line when two points (coordinate pairs) #(x_1, y_1)# and #(x_2, y_2)# are given is #m=(y_2-y_1)/(x_2-x_1)#, where #m# denotes the slope of the line.

Applying this formula, we get:

#m=(-9-6)/(-6-(-9))#

#m=(-15)/(-6+9)#

#m=(-15)/3#

#m=-5#
