Use of this system is pretty intuitive. Enter your linear programming problem (with two variables x and y) in the space below, and press "Solve" to solve without showing the feasible region, or "Graph" to solve it and also show the feasible region for your problem. Press "Example" to see an example of a linear programming problem already set up.

• To solve a linear programming problem with more than two unknowns, use the Simplex Method Tool.
• In some browsers, you might have to jiggle the graph window size a little to make the graph appear.
• Warning The graphing routine will tax your browser, and it might crash and cause your computer to crash with it. Thus, you should save all your work before pressing "Graph"..
