How to Solve Linear Programming Problems Graphically

TL;DR

To solve linear programming problems graphically, utilize the corner point method, which involves graphing constraints to identify the feasible region. The optimal solution is found at the corner points of this region, where the objective function yields its maximum or minimum value. This method is effective for problems with two variables.
