One quick question

How might one draw a rectangle on a TI-83 plus... without saving it as a picture or anything.. like to put it in a program "draw this rectangle" or whatever...
Thanks.
Use the line function to draw 4 lines between the 4 corners of the rectangle. Then use DispG (or whatever it is for a Ti-83) to display the graph. Probably insert a pause statement in there after that or something - depends what you want to do.

That's not what im trying to accomplish. I'm trying to make it to where I can put it on one line, and it appears, rather than go each step individually, when it draws it.

What do you mean by this? You can have the 4 lines drawn simultaneously, so you won't even be able to notice that they're all drawn separately.
Do it within a program. Have the user input the 4 points. Draw the lines. Display the graph. Done.
:Line(X1,Y1,X2,Y1):Line(X2,Y1,X2,Y2):Line(X2,Y2,X1,Y2):Line(X1,Y2,X1,Y1)^^^ All on one line (not that it would make a difference if it were on four lines).
All of this material is definitely covered in the manual.
When it comes down to it a computer can only perform one instruction at a time. Thus, if you want to draw a box, you tell it to draw each line according to the coordinates you give them. It usually happens so fast that you don't notice it. So your code would do this:
Draw line 1;
Draw line 2;
Draw line 3;
Draw line 4;
Calculate the area;
Fill in the area;
All those steps would happen so fast that you'd just see the end result.

To fill you need to use the shade function, which sadly only takes two function values as parameters. Since a rectangle is defined by 3 4 functions, I don't know if you'll be able to shade it without altering the pixel data... which is really slow unless you're using ASM, and I gather you're not...
EDIT: what was I thinking? A rectangle is defined by 4 functions... not 3. Pardon the error!
