Please use graphical method to find the FEASIBLE REGION. Please LABEL the 3 constraints in your graph and indicate all the points you used. 2). Please draw an objective function line (must write the equations here) in the graph of 1). Mark the optimal solution as a star. 3). Please list the system of two equations (crossing at the optimal solution point) 4). Please get the optimal solution of 3): How much is X1 and X2? You need to indicate the maximized output of the objective function
