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.
