vertical line with equation #x = 3#

equation for slope: #m = (y_2 - y_1)/(x_2 - x_1)#

#m = (9 - (-5))/(3 - 3)# = #14/0#

slope is undefined since division by 0 is not possible, hence
vertical line

Slope is undefined.

The formula for slope is

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

For the coordinate points #(3,9) and (3,-5)#
#x_1 = 3#
#x_2 = 3#
#y_1 = 9#
#y_2 = -5#

#m = (-5-9)/(3-3)#

#m = -14/0#

The slope is #m =#undefined

This line is a vertical line with no run, change in x.
