vertical line with equation x = 3

Explanation:

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.

Explanation:

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.
