Graph Y-Values with TI89 Titanium Graphing Calculator

[chemic_23]

Hello,the <Diamond> + F1 menu allows me to plot only Y= graphs.
I just want to ask if how do I graph in terms of y? is there anyway or you need to really graph it in terms of x? thank you very much...

You can try using the parametric mode to graph like this.

Or another way would be to use the solve() function on the calculator and solve the equation so that you are allowed to enter it in Y editor.
