Graphing Inequalities on the TI-82 Topic Index | Algebra Index | Regents Exam Prep Center

If you are still using the TI-82 graphing calculator, you may need a refresher on how to graph inequalities, as it requires several steps.

 Instructions for graphing inequalities on the TI-83, TI-83+ and TI-84+ can be found at Graphing Linear Inequalities

If you have the "older" TI-82, the instructions are below:

Using the TI-82 Graphing Calculator

 1.  Solve to isolate the y variable:                             Enter Y1= 2x + 2 2.  Hit DRAW ----2nd PRGM            Choose #7 Shade ( The parameters for Shade are: Shade(lowerfunc, upperfunc, resolution,  xleft, xright)      (resolution ranges from 1 to 9  where 1 is solid)      (xleft, xright are optional) Shade(Y1, 10, 5) To get the "Y1" to appear, go to Y-Vars, Function, and choose Y1 If using Zstandard, use y =10 as upperfunc OR y = -10 as lowerfunc 3.  Choose DRAW #1  ClrDraw  between graphs to clear the screen      OR run "DEFAULTS" program (if you have it on your calculator) to clear the screen.
