Question

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)

Answer 1

I would draw 2 lines. one horizontal and one vertical to "isolate" points D and E can you do that ?I already did this problem... can you follow the instructions for that post?i think it should be intersecting D.the lines does not have to go through the points. we need to say the points are above or below one line and to the left or right of the other.
