What's the question?
OpenStudy (anonymous):
The coordinate plane below represents a city. Points A through F are schools in the city.
OpenStudy (anonymous):
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. (5 points)
Part B: Explain how to verify that the points B and C are solutions to the system of inequalities created in Part A. (3 points)
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. (2 points)

im not sure.
OpenStudy (xhawaiiangirlx):
okay well let me show you an example
OpenStudy (xhawaiiangirlx):
First off Inequality tells us about the relative size of two values.
OpenStudy (anonymous):
okay
OpenStudy (xhawaiiangirlx):
Example: Alex and Billy have a race, and Billy wins!
What do we know?
We don't know how fast they ran, but we do know that Billy was faster than Alex:
Billy was faster than Alex
We can write that down like this:
b > a
(Where "b" means how fast Billy was, ">" means "greater than", and "a" means how fast Alex was)
