x=-2 does not have a slope does it?

• math -

sure it does, m = intinity
graph it, straight up and down parallel to y axis crossing x axis at x = -2

• math -

So the slope would be all numbers?
Or is it just undefined?
I have to give exact numbers.

• math -

There is no exact number but oo. The slope of a vertical cliff is infinite.
