I just bought this graphing calculator. I have TI-89 Titanium my professor Mr.Abdullatif told me that I am able to enter formuals in it so I can do the problems quicker. This is an example I want the calculator to make like x+2y=-10 into slope intercept form. But no where in the manual says how to do that. I am just wondering if anyone on here knows how to do it. Because I didn't spend 150 dollars on a damn clauclator for nothing.
Also if this thread doesn't belong here if one of the mods would move it to some where else where its exposed to be I would apperciate it.
I changed the equation.
