Question

The graphical method of solving a linear programming model can be used:

a) When a problem involves only two decision variables
b) For any model that is described with the algebraic approach
c) Only when the optimal solution is found at the origin (0,0)

Answer 1

The graphical method of solving a linear programming model can be used for any model that is described with the algebraic approach. It is not limited to problems involving only two decision variables, and it does not require the optimal solution to be found at the origin (0,0).

Step-by-step explanation:

The graphical method of solving a linear programming model can be used for any model that is described with the algebraic approach. It is not limited to problems involving only two decision variables, and it does not require the optimal solution to be found at the origin (0,0).

The graphical method involves plotting the constraints and objective function on a graph to find the feasible region and the optimal solution. The optimal solution is represented by the point of intersection of the constraints that maximizes or minimizes the objective function. For example, if we have a linear programming model with three decision variables, we can still use the graphical method by plotting the constraints and objective function in three-dimensional space.
