1. Unit 1b Section 3-3 Solving Systems of Inequalities

2. Solving Systems of Inequalities The solution to a system of inequalities is not where the graphs intersect but where the ___________ intersect (all coordinates in the overlapped region make up the solution set). You can verify your answer by checking ________. TEST POINTS: choose any ordered pair that is in the overlapping shaded regions (not on either line), and substitute the x and y values to verify that they are both true statements. test points shaded regionS

3. Solving Systems of Inequalities TEST A POINT: ( 5, 0 ) True What do you think would happen when you test ( 0, 5 )? True False Explain the results of the test point ( 0, 5 ) and why this is the case.

4. TEST A POINT: ( 0, 4 ) What are two other points you could have used to test?? Could you use ( 0, 2 )? ( 0, 5 )? Explain. Solving Systems of Inequalities True
