What formula is used to create the graph? That is where I am stuck.

For the Valencia Products model in Problem 1, graph the constraints and identifythe feasible region. Then identify each of the corner points and show how increasing the objective function value identifies the optimal solution. Valencia Products makes automobile radar detectors and assembles two models: LaserStop and SpeedBuster. The firm can sell a it produces. Both models use the same electronic components. Two of these can be obtained only from a single supplier. For the next month, the supply of these is limited to 4,000 of component A and 3,500 of component B. The number of each component required for each product and the profit per unit are given in the table. 1. Components Required/Unit B 6 10 Profit/unit $24 $40 LaserStop SpeedBuster 18 12 a. Identify the decision variables, objective function, and constraints in simple verbal statements b. Mathematically formulate a linear optimization model
