A dual value (shadow price) for a constraint in a maximization problem means: a) as the right hand side value decreases, the objective value function will increase b) as the right hand side value increases, the objective value function will increase c) as the right hand side value increases, the objective value function will decrease d) as the right hand side value increases, the objective value function value will stay the same

B. As the right hand side value increases, the objective value function will increase

Step-by-step explanation: The dual value also known as the shadow price of a commodity that is not commonly priced in the market, the price of the commodity is not known. The dual value of a constraint can also be described as the rate of change of the objective function to the constant value which is placed at the right hand side of that constraint. The shadow price for a constraint in a maximization problem is Described as the Increase experienced at the Objective function when the right hand side value increases.

Slope:

-2-1/2-(-2)=

-3/4

Slope intercept form:

y-1=-3/4(x-(-2))=

y-1=-3/4(x+2)
