The slope of the level curve for the objective function value can be changed by
A) increasing the value of the decision variables.
B) doubling all the coefficients in the objective function.
C) increasing the right hand sides of constraints.
D) changing a coefficient in the objective function.

Question

Quizplus · Accepted Answer

The slope of the level curve for the objective function value is determined by the coefficient of the decision variable in the objective function. Therefore, changing a coefficient in the objective function will change the slope of the level curve. Increasing the value of the decision variables or the right hand sides of the constraints will not directly affect the slope of the level curve. Doubling all the coefficients in the objective function will change the scale of the level curve but not the slope.
