I'm so insanely stupid.

part a: using the graph above, create a system of inequalities that only contain points b and c 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 b and c are solutions to the system of inequalities created in part a.

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.
