Case Study

Logistics Planning for Distribution Center

Based on the provided case study and standard rules of graphing systems of inequalities, recall and state:

  1. What mathematical feature of the equations y=14x+2y = -\frac{1}{4}x + 2 and y=14x+1y = -\frac{1}{4}x + 1 confirms that the two boundary lines are parallel?
  2. What rule determines whether the boundary lines for y14x+2y \leq -\frac{1}{4}x + 2 and x+4y4x + 4y \leq 4 should be solid or dashed? State whether they are solid or dashed in this case.
  3. Recall how to perform a test point verification using the origin (0, 0) for the first inequality, and state if (0, 0) is part of the shaded region.
  4. Recall the rule for the intersection of regions with parallel boundary lines shaded in the same direction, and identify which single inequality's solution represents the solution of the entire system.
