How do you graph constraints in linear programming?
The Graphical Method

Step 1: Formulate the LP (Linear programming) problem.
Step 2: Construct a graph and plot the constraint lines.
Step 3: Determine the valid side of each constraint line.
Step 4: Identify the feasible solution region.
Step 5: Plot the objective function on the graph.
Step 6: Find the optimum point.
