Answer: The slope is undefined

Given the following points

A = (6, 1) and B = (6, -9)

slope = rise / run

rise = y2 - y1

run = x2 - x1

Therefore, slope can be written as

slope = y2 - y1 / x2 - x1

from the above points, let x1 = 6, y1 = 1, x2 = 6 and y2 = -9

slope = -9 - 1 / 6 - 6

Slope = -10 / 0

Slope = undefined
