Complete Problem 1 on pages

2. Objective - To graph systems of linear inequalities.

4. Determining a Solution
Solutions to a system of inequalities are all the points in the double shaded region.
You can always PLUG IN the given point into BOTH inequalities to determine if it is a solution.
REMEMBER: The point must make BOTH inequalities TRUE to be a solution to the system.

6. Graph a system of 3 linear inequalities.

7. Write a system of linear inequalities that describe
the shaded region. 1) 2)

9. Write a system of linear inequalities that describe
the shaded region. 3) 4)
