How do I enter formulas into this calculator

[Brut]

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.

Enter this formula and you should be good to go

2y+3x-24=0 into slope intercept form

Umm i do know (think) you have to set your X's and Y's seperatly, (you dont enter them on the same screen) look for like your FUNCtion button and go with that. Hoped I helped any....y=-2/x-5 so the graph would be set at -5 then count down 2 and over to the right 1 for your slope.....WOW only a year outta school and i barely if any rem that shit.
