The slope is undefined

Explanation:

Given: (-10, -9), (-10, 8)#

slope $= m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{8 - - 9}{- 10 - - 10} = \frac{17}{0} = undefined$ $= m = (y_2 - y_1)/(x_2 - x_1) = (8 - -9)/(-10 - -10)= 17/0 = "undefined"$

The slope is undefined. This means the line is a vertical line.
