Slope: #m=0#

Explanation:

Slope is defined as the change in #y# divided by a corresponding change in #x#.

Given two points #(x_1,y_1)# and #(x_2,y_2)#
the change is #y# is #Delta y = (y_2-y_1)#
and the corresponding change in #x# is #Delta x = (x_2-x_1)#

For the specific points #(-9,-1)# and #(-2,-1)#
we can see that the slope #m# is
#color(white)("XXX")(Delta y)/(Delta x) = ((-1)-(-1))/((-2)-(-9)) =0/7=0#
