    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!
