Question

A vertical line has a run which is
A. 1
B. zero
C. undefined
D. -1

Answer 1

Vertical slopes are undefined.

Answer 2

I submitted "undefined" and it was incorrect

Answer 3

Well there needs to be one answer :/

Answer 4

That's where I'm stuck

Answer 5

-1/0 is -1, I honestly don't know the rules behind it, but I remember it shocking me when I was younger, because I was always taught that it had an infinite slope.

Answer 6

I know but it was incorrect when I submitted that, thats why I came here to see what other people think

Answer 7

Vertical slopes are undefined, yes, but the slope itself is explained as -1/0, the negative reciprocal of a horizontal slope of 0

Answer 8

Oh sorry it says "RUN"

Slope is rise over run. Stupid worded question.

The run is zero.
