Question

find the slope if it exists
x=-6

Answer 1

infinity or undefined

Answer 2

I haven't heard of the infinity thing before - what is that? I'm curious about it.

Answer 3

infinity???

Answer 4

That's what I was thinking. A vertical line has no slope or undefined slope. you can even see if if you take 2 points on a straight line and try to calculate slope. you end up with zero in the denominator. I'm not sure where infinity would fit in this.
