1. Mon, 3/19 SWBAT… graph systems of inequalities
Agenda
WU (5 min)
Tests (10 min)
Writing linear inequalities from graphs (HW#1) – 6 examples (20 min)
Warm-Up:
HW#1: System of linear inequalities
Read the agenda and write your HW in your planner for the week 1 1

3. 1.) Given the inequality graphed below:
a.) Write an inequality statement.
b.) Name one ordered pair that is not in the solution set.
c.) Name one ordered pair that is in the solution set.

4. 2. Given the inequality graphed below:
a.) Write an inequality statement.
b.) Name one ordered pair that is not in the solution set.
c.) Name one ordered pair that is in the solution set.

5. 3.) Write a system of inequalities for the dark blue solution shown on the graph below. (Hint: you should write 2 different inequalities – one for each graph)
b.) Name one ordered pair that is in the solution set.
c.) Name one ordered pair that is not in the solution set.
