The coordinate plane below represents a city. points a through f are schools in the city.

part a: using the graph above, create a system of inequalities that only contain points d and e 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 d and e are solutions to the system of inequalities created in part a. (3 points)

part c: timothy can only attend a school in his designated zone. timothy's zone is defined by y < 3x − 3. explain how you can identify the schools that timothy is allowed to attend. (2 points)
