Part A: Using the graph above, create a system of inequalities that only contains points B and C in the overlapping shaded
regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)
Part B: Explain how to verify that the points B and C are solutions to the system of inequalities created in Part A. (3 points)
Part C: Lisa can only attend a school in her designated zone. Lisa's zone is defined by y> 2x + 5. Explain how you can identify the
schools that Lisa is allowed to attend. (2 points)
