Linear Programming Graphical Method Quiz

What is the graphical method used for in linear programming?

• To calculate the slope of the objective function

• To determine the intercept of the constraints

• To visually represent the feasible region and find the optimal solution.

• To plot the decision variables

In the graphical method, what does the feasible region represent?

• Infeasible solutions

• Randomly generated points

• Only the optimal solution

• All possible solutions that satisfy the constraints

How is the optimal solution found in the graphical method?

• By flipping a coin

• By following a random path

• By choosing the highest number

• By identifying the corner point of the feasible region that optimizes the objective function.

What does the objective function represent in linear programming?

• The objective function represents the constraints in linear programming.

• The objective function represents the feasible region in linear programming.

• The objective function represents the quantity that needs to be maximized or minimized in linear programming.

• The objective function represents the decision variables in linear programming.

What is the significance of the slope of the objective function line in the graphical method?

• The slope of the objective function line determines the feasibility of the solution.

• The slope of the objective function line indicates the number of variables in the problem.

• The slope of the objective function line reflects the accuracy of the constraints.

• The slope of the objective function line represents the rate of change of the objective function value.

What happens if the feasible region in the graphical method is unbounded?

• The method is invalid.

• There is no optimal solution.

• The solution is unique.

• The problem is unsolvable.

How are constraints represented graphically in the graphical method?

• By adding more variables to the graph

• By shading the feasible region

• By using circles instead of lines

• By drawing lines or boundaries

What is the role of the origin in the graphical method of linear programming?

• The origin is irrelevant in the graphical method of linear programming

• The origin serves as a reference point for determining the feasible region and optimal solution.

• The origin represents the maximum value in linear programming

• The origin is used to plot the constraints in linear programming

What is the difference between a feasible solution and an optimal solution in linear programming?

• A feasible solution is always the same as an optimal solution.

• A feasible solution satisfies all constraints, while an optimal solution is a feasible solution that optimizes the objective function.

• A feasible solution is the most complex solution, while an optimal solution is the simplest.

• An optimal solution satisfies all constraints, while a feasible solution maximizes the objective function.

How can the graphical method be used to solve linear programming problems?

• The graphical method can be used to solve linear programming problems by visually representing constraints and the objective function on a graph to find the optimal solution.

• The graphical method involves solving equations algebraically

• The graphical method cannot be used for linear programming

• The graphical method only works for non-linear problems
