Consider the following LP. On a piece of paper, solve this problem using the graphical solution method fincluding identifying the feasible region, drawing the isoquant lines. identifying and labeling the improving direction, and finding/labeling the optimal solution). Upload a picture of your graph and solutions under Upcoming Assignments. Test 1 file upload on Canvas after you submit the test (no later than 5 minutes after your submission). DO NOT upload here! Minimize 5x+7y, Subject to 2x+3y30x+y12y11x0,y0. a) Graph the constraints and identify the feasible region. b) Draw the isoquant representing all combinations of x and y that make the objective function equal to 105 . c) Identify the improving direction and label it in your graph. d) Identify the optimal solution and label it on your graph
