#slope = 8#

Explanation:

From the formula of the slope

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

#(9,8),(7,-8)#
#(x_1,y_1),(x_2,y_2)#

#color(red)(x_1 = 9)#
#color(blue)(y_1 = 8)#
#color(green)(x_2 = 7)#
#color(brown)(y_2 = -8)#

#= (color(brown)(-8)-color(blue)(8))/(color(green)(7)-color(red)(9)) = (-16)/-2=8#
