Question

What is the reason for the b) answer? I cannot understand it. Please, if possible visualize why it is correct.

1. Suppose that p, q ER are both constants and consider the following linear program:
maximize pr₁+qx₂
subject to
₁ + 3x2 ≤ 6,
3x1 + x2 ≤ 6,
x₁ + x₂ ≥ 1,
X1, X2 20
(a) Sketch the feasible region for these constraints.
Solution:

(b) Find a value for the constants p and q so that x₁ = 3/2, x₂ = 3/2 is the unique
optimal solution of the resulting program.
Solution: By looking at the picture, one option is to set p = 1, q= 1, which
gives us a direction (1, 1) that makes this the only optimal solution.
