Which of the following statements concerning a linear programming problem is NOT true?
A) When using the graphical method for solving a linear programming problem a maximum of 2 variables can be used
B) When using the graphical method for solving a linear programming problem one, but not both variables can be negative
C) When using the graphical method for solving a linear programming problem trial and error is an acceptable method for finding the optimal point
D) When using the graphical method for solving a linear programming problem an algebraic method can be used to confirm the optimal point

The graphical method for solving a linear programming problem requires both variables to be non-negative. This is because the feasible region, which is determined by the constraints of the problem, is represented in the first quadrant of a Cartesian coordinate system where both axes represent non-negative values of the variables.
