Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 2x − 7 y ≥ -1/2x + 3 is the point (3, −7) included in the solution area for the system? justify your answer mathematically.

No, it is not in the solution area for the system.

The point only works in one of the inequalities. 

It doesn't work in the inequality: y > -1/2x+ 3

We can put it in to test it:

-7 > (-1/2)3 + 3
-7 > -1.5 + 3
-7 > 1.5  This is a false statement, therefore it is not part of the solution.
