TI-84 programming

Hey, I was wondering if anyone here knew how to program the TI-84/TI-83 calculator? I have already made a few programs on it, but I cannot figure out how to draw lines. Could someone please give me some hints?

Thanks

can you give a link to the website for this calc.?

Get the user manual for the TI-83/84 Plus/Silver edition from the TI website.

It has every function you would need. I don’t know the exact name of the function I used (don’t have the calculator handy) but I think you had to use something like Draw(), Line(), Circle(), something around there and then ClrDraw() to clear the drawing area… I could be way wrong… But its worth looking up. Good luck!

i currently have a Ti83+, and to draw lines, all you need is four coordinates, (x1,y1) and (x2,y2).

Thank you all for your help. The site is… http://www.ticalc.org/
