## What is LP Grapher?

Solves linear programming (LP) problems graphically. Enter an LP problem in two variables and press Solve to see the corner points, the lines passing through each, the values of the objective function, and the optimal corner. Press Show Graph to see the graph of the feasible region with the optimal corner highlighted.

Includes links to the Waner/Costenoble FiniteMath web site and its tutorial on graphical solution of LP problems.
