Solve the following linear programming model graphically:

Maximize    Z = 3 x1 + 2 x2Subject to: 

2 x1 + 4 x2 ≤ 22-x1 + 4 x2 ≤ 104 x1 – 2 x2 ≤ 14x1 – 3 x2 ≤ 1x1, x2 ≥ 0

(a)  Solve the Linear programming model graphically, gives all the corner points along with the values of Z and identify which one is optimal. Give reasons.

(b)  Find the value of the slack and surplus variables at the optimal solution only.
