So I have to do this problem for homework. However, my book doesn't show us how to draw a graph that involves a z-axis as well as an x and y-axis. It assumes that you know how, and I haven't done this before so I would appreciate any help.

It's hard to say without an example... There are different ways of doing it, or at least to my memory anyway.
