Whether the statement "I need to be able to graph systems of linear inequalities in order to solve linear programming problems" makes sense or not.

Let $$\displaystyle{z}={a}{x}\ +{b}{y}$$ be an objective function that depends on x and y. Also, z is subject to a number of constraints on x and y. If a maximum or minimum value of z exist, the linear programming problem can be solved as follows:
