1. All of the following statements about a redundant constraint are correct EXCEPT

A redundant constraint does not affect the optimal solution.

A redundant constraint does not affect the feasible region.

Recognizing a redundant constraint is easy with the graphical solution method.

At the optimal solution, a redundant constraint will have zero slack.

2. A negative dual price for a constraint in a minimization problem means

as the right-hand side increases, the objective function value will increase.

as the right-hand side decreases, the objective function value will increase.

as the right-hand side increases, the objective function value will decrease.

as the right-hand side decreases, the objective function value will decrease.
