The coordinate plane below represents a city. points a through f are schools in the city.
graph of coordinate plane. point a is at negative 3, negative 4. point b is at negative 4, 3. point c is at 2, 2. point d is at 1, negative 2. point e is at 5, negative 4. point f is at 3, 4.

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

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