i have to graph some things on my ti-83, and i have to graph x=2 how am i supposed to do that if i can only type in y= stuff?

you can only do y = stuff? i would think the TI can graph x = stuff.

anyway, you can just imagine it being there, or graph it yourself. x = 2 is just a vertical line that cuts the x-axis at 2

I know that the 83 and 84 can...but I forget how to do it in rectangular mode... XD

However, if you graph $r=2\sec(\theta)$ in POLar mode, then it will graph a vertical line through x [in this case, r] = 2.

Hope this helps!
