In determining the optimal solution to a linear programming problem graphically, if the objective is to maximize the objective, we pull the objective function line down until it contacts the feasible region.

Question

Quizplus · Accepted Answer

This is correct. When maximizing, we want to move the objective function line (often represented by a dotted line) upwards until it touches the highest possible point of the feasible region. Similarly, when minimizing, we want to move the objective function line downwards until it touches the lowest possible point of the feasible region.
