• I CAN graph systems of linear inequalities

Use Graph Paper

Let's review:• Graph the solution space of: −4x − 3y > -9

Systems of inequalities:Graph the system of linear inequalities. How can we check our answer?

y ≤ 2 Inequality 1

y > 2x - 1 Inequality 2

Systems of inequalities:Graph the system of linear inequalities. How can we check our answer?

3x + y < −2 Inequality 1

3x + y > 4 Inequality 2

Let's try some!• Work together to graph your system of inequalities on

the wall. Be sure to write down the original problem. Check your answer (show your work)!

3. y ≥ −x + 4 4. y > 2x − 3 5. −2x + y < 4

x + y ≤ 0 y ≥ x + 1 2x + y > 4

2. x + y > 4

y ≥ (3/2)x - 9

6. 2x + y ≤ 5

y + 2 > -2x
