The coordinate plane below represents a city. Points A through F are schools in the city.

Part A:Using the graph above, make a system of inequalities that only contains points D and E in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above.

Part B:Explain how to verify that the points D and E are solutions to the system of inequalities created in Part A.

Part C:Timothy can only attend a school in his designated zone. Timothy's zone is defined by y

A D E C + -6 -5 -4 -3 -2 -1 1 2 3 4 5 6 B F + +
