Consider the following linear programming problem. The objective function is given by min z = 4.01 + 602. This is subject to constraints that give the following feasible region. 22 (2,5) 5 (3.5, 4) 3 2 (2,1) +21 2 3 (a) (2 points) What is the slope of every isocost line? Clearly show your work. (b) (2 points) What is the optimal solution? In other words, what 11 and 22 produce the optimal z-value, and what is the optimal z-value? Clearly show your work that supports how you found your
