Solution 30331: Graphing Linear Inequalities on the TI-Nspire™ CAS Handheld or Software.

How do I graph a linear inequality on the TI-Nspire CAS handheld or software?

The f1(x) = does not allow an inequality to be directly entered into the calculator. However, you can delete the = sign and key in styles feature of inequality to get the solution.

The example below will demonstrate how to graph a simple linear inequality.

Example: 3x+2y<=6 to be graph.

• First, solve for y by using the solve command.
• Under the Calculator application press menu>3: Algebra>1: Solve (3x+2y<=6,y).
• Enter the answer in the editor as y<=-3x-2/2

- Select graphs f1(x)= delete = to insert less then or greater then sign y<=(-3x+2)/2 and press Enter
