SECTION 6-5 : LINEAR INEQUALITIES

2. Determine whether the ordered pair is a solution of the linear inequality.
1) y > 3x – 5 (-4, -13)
Answer : yes, -13 > -17
2) y < -x + 7 (9, -1)
Answer : no, -1 is not less than or equal to -2

3. ALGEBRA I - SECTION 6-5 (Linear Inequalities)
Graph each inequality.
3) y < x - 2
First, graph the line y = x – 2.
Do the points on the line make the inequality true? If so, draw a solid line to show those points satisfy the inequality. If not, draw a dotted line.
Inequalities involve shading. In what direction do we shade this graph? How can we do this?

4. 4) 3x – y < -1
Remember, when you multiply or divide an inequality by a negative number, switch the direction of the inequality.
< >

5. 5) y > 4

6. 6) x < -3
