Graphing
To graph the inequality , follow the three-step procedure: Step 1 — Graph the boundary line. Replace the symbol with to get the boundary line . Since the inequality is strict (<$), draw a dashed line. Step 2 — Test a point. Use (0, 0)2(0) - 3(0) < 60 < 6(0, 0)(0, 0)$$, which is the region above the dashed boundary line.

A small business owner is using a linear inequality to model the maximum number of hours two employees can work without exceeding a weekly budget. To visualize this constraint on a graph, place the following steps in the correct order as they would be performed according to the standard procedure.
A logistics coordinator is using linear inequalities to map out delivery zones based on fuel costs and time constraints. Match each graphing rule with the specific condition that triggers it according to the standard procedure.
A facility manager is graphing a linear inequality to ensure office layouts comply with occupancy codes. While following the standard three-step graphing procedure, the manager identifies that a chosen test point is not a solution to the inequality. To correctly represent the solution set, which region of the graph should the manager shade?
An inventory manager is graphing a linear inequality to model warehouse storage capacity. If the boundary line for the inequality passes directly through the origin , the manager can still use as the test point to determine which side of the line to shade.
Interpreting the Results of a Linear Inequality Graph
An urban planner is using the linear inequality to model the maximum population density of a residential block. When following the standard procedure to graph this constraint, the planner first replaces the inequality symbol with an equals sign to obtain the equation of the ________.

A marketing manager uses a linear inequality to model the possible combinations of social media ads and print ads that can be purchased within a fixed monthly budget. After the manager graphs the boundary line and shades the appropriate region, what do the ordered pairs located within that shaded region represent?
A marketing analyst is graphing a linear inequality to visualize a budget constraint between two advertising channels. To determine which side of the boundary line to shade, the analyst prepares to select a test point according to the standard three-step procedure. What is the mandatory requirement for the point the analyst chooses?

A facility manager uses the inequality to manage the occupancy levels of two different conference halls ( and ). When graphing this inequality to represent the occupancy limit, which of the following correctly describes the type of boundary line to be drawn and the result of using as a test point?
A logistics analyst uses the linear inequality to model the cost constraints between two different shipping routes. To correctly visualize the feasible solution region on a graph, the analyst must follow a specific set of steps. Arrange the following steps in the correct order according to the standard procedure for graphing this inequality.
An operations analyst is using the linear inequality to monitor resource allocation limits between two manufacturing lines. To ensure the graph accurately represents the feasible production region, match each component of the graphing process with its corresponding result for this specific inequality.
