Question

Find the slope of the line through the points (13, 15) and (13, 19). Then find the slope of the line parallel and the line perpendicular.

Answer 1

We must find the slope of the original line using slope formula*.

`m = (19 - 15)/(13 - 13) = (5)/(0) = 0`

Because the given points have the same x-coordinate, the slope is 0.

Given that the original line doesn't have slope, the other two lines won't have one either.
