The slope for the pair of coordinates is undefined.

The coordinates are:
#(7,3) = color(blue)(x_1 , y_1#

#(7, -5) = color(blue)(x_2 , y_2#

The slope is calculated using formula:

Slope #=color(blue)((y_2 - y_1) / (x_2 - x_1)#

# = ( -5 -3 ) / ( 7 - 7)#

# = ( -8 ) / (0)# = not defined

The slope for the pair of coordinates is undefined.
