Let first look at trying to graph, for example, y=2x. I'm guessing you would have no problem with this, but let's take another look at what we're really doing. The idea is to find every possible pair of numbers which satisfy the equation and plot them on a set of axes.

When x=1, we're looking for the value of y which makes y=2x true. This only works when y=2, so the point (1,2) is ...
