The graphing calculator program which comes with every Power Macintosh computer is a very powerful tool for doing algebra. This activity will help you to learn how to use this program to graph inequalities.
When you start the graphing calculator, you should see a window similar to this:
You type expressions and equations in the top part of the window. Graphs appear in the bottom part of the window. The buttons on the lower left allow you to zoom in and out. You can move the graph by dragging the axes with your mouse.
Graph the following inequalities and copy those graphs onto graph paper:

Create your own systems of inequalities with graphs shaped like a kite, a square, a trapezoid, and a pentagon. Record each system of inequalities and copy your graph onto graph paper. Can you create a system of inequalities with a graph shaped like a five or six pointed star? I can.
Graph the following systems of inequalities and set n to run from 0 to 2 with 20 steps:
Graph the following systems of inequalities and set n to run from -2 to 2 with 20 steps:
Create your own animated system of inequalities. Make it as interesting as you can!
