If I called [latex]x_{1}[/latex] and [latex]x_{2}[/latex] by another name, say x and y, would you be able to do it? The labelling of the variables is meaningless.

Still though, how do you graph them if you don't have any numerical value assigned to the variable?

They're both lines but what their slopes and intercepts are depend on the sign of the different constants. So number of different possibilities when graphing it.

So would it suffice to just graph one of the possibilities?

Nope, you'd have to do them all for completeness. The first question kind of implies that anyway.
