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 y0, and since we cannot divide by 0, we call the slope for this (and any other vertical lines) is undefined
