a vertical line is undefined because it basically means that you are everywhere all at one time, which is kind of impossible. For example, if you have a distance vs. time graph, it means that at one time, you are at all different distances at once.

The point is, this is undefined. My above explanation probably made no sense whatsoever

That is correct.  :)
0 rise, any amount of run:  0/N = 0.
