The coordinate plane below represents a community. points a through f are houses in the community. graph of coordinate plane. point a is at 1, 3. point b is at 3, 1. point c is at 3, negative 3. point d is at negative 4, 2. point e is at negative 1, 5. point f is at negative 3, negative 3. part a: using the graph above, create a system of inequalities that only contains points a and b 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 a and b are solutions to the system of inequalities created in part a. (3 points) part c: billy wants to live in the area defined by y < 3x − 6. explain how you can identify the houses in which billy is interested in living. (2 points)
