I submitted "undefined" and it was incorrect

zarkam21 · Answer

Well there needs to be one answer :/

That's where I'm stuck

-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.

zarkam21 · Answer

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

jadeishere · Answer

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

Oh sorry it says "RUN"

Slope is rise over run. Stupid worded question.

The run is zero.
