TI-89; How do I graph?

I just got a TI-89 calculator and am having trouble figuring out the graphing function. For example, y=x-5, exactly what do I have to enter to look at that graph. I got one graph to show up, but it kept repeating as I entered new graph's equations, now I am getting "undefined variable" after I enter y=x-5, then diamond, then F3.

press mode -->graph
and make sure it is on function, not polar or something else
diamond
enter eq on line 1
F2 (and any options you want) enter

diamond F1 returns to eq.
erase equations you don't want graphed.
