Visualizing Delivery Constraints: Graphical Systems of Inequalities
An operations coordinator at a local courier service is updating the company's dispatch map to define a "Priority Delivery Zone." On a coordinate grid, this zone is modeled by the system of linear inequalities:
To ensure that newly hired dispatch assistants can read and verify the map correctly, you need to write a reference guide outlining the graphing process from memory.
In your essay, recall and describe the step-by-step rules used to graph this system of inequalities. Specifically, address the following four points:
- State whether the boundary lines for and must be drawn as solid or dashed, and explain the rule for making this decision.
- Describe how to use the origin (0, 0) as a test point to determine which side of each boundary line to shade. Show the resulting inequalities when (0, 0) is substituted into both and .
- Explain how to identify the final "Priority Delivery Zone" on the graph, and recall whether the specific intersection point of the two boundary lines is included in this zone.
- State the purpose of selecting an additional test point within the overlapping shaded region.

An operations manager at a distribution center is mapping out a 'Storage Optimization Zone' for inventory. Let represent the number of standard storage racks, and let represent the number of oversized storage racks. The constraints for these racks are modeled by the system of linear inequalities and .
To visualize this, the manager graphs the system on a coordinate grid. They plot the boundary line as a dashed line and shade below it, and they plot the boundary line as a dashed line and shade above it.
Because both boundary lines are dashed, the specific coordinate point where the two boundary lines intersect is ____ in the final overlapping region that represents the 'Storage Optimization Zone'.
