Question

What is the slope of the line x=-2?

Answer 1

It is a curve parallel to Y-axis. Its slope is `oo`

Explanation:

Given -

`x=-2`

It is a curve parallel to Y-axis. Its slope is `oo`

Answer 2

The slope is undefined

Explanation:

Let's graph this line:

So, slope is change in `y` over change in `x`, or rise over run. So, if the graph goes up `1` unit, it moves over `0` units. That's the same for if `y` is `60` or `.778`. `x` is always `0`

So, no matter what, the slope is `y/0`, and since we cannot divide by `0`, we call the slope for this (and any other vertical lines) is undefined
