x-3x=9
Yes. A graphing calculator has lots of options for mathematical calculations, but in addition, it has a relatively large screen, and options to graph functions.
change it to polar mode and then plot r = any constant
On all of the graphing calculators, they have the graphing things on it. First to make a graph, you need an equation. when you have the equation ready, you just press the button on the top left (for the most calculaters), the "y=" button. Then you will get a lot of empty lines for you to put the equations on. After you type all the equations, you will have to press the "graph button on the top right. then you will get a graph.
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.

Graphing calculators are true to their name: they can graph out equaitions. Letting the calculator graph out equations is a lot easier than plotting and drawing your own graph, but you do not NEED a graphing calculator. Besides that, their functions are similar to other scientific caculators.

Here is a great site that will tell you everything you know about graphing calculator programming, and its got programs there to! See the related link, "Graphing Calculator Programming".

On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.
Go to the y= button, and type in your equation by the y1 (if there's 2 equations, press enter and type the 2nd one in by the y2). Then press graph.
It will depend on the class. Nothing is impossible without the TI83, but some classes might require it so you can graph and write programs to go along with the math curriculum.
Graph the equation then find the x intercepts.
