slope m = diffy/diffx = 2/0
m is undefined, or infinite.
The line is "vertical", parallel to the y-axis.
------------------
PS m = 0 is parallel to the x-axis.

The slope is undefined since you CANNOT divide by zero. Ie 2%2F0 is not allowed.


Note: This is NOT the same as 0%2F2 which is in fact zero. It's easy to mix up the two.
