2.6 Linear Inequalities in Two Variables
DO NOW:
Check whether the ordered pair is a solution of 4x – 2y ≥ 8
a) (3, 3) b) (-2, -9)

2. Then, Test a point like (0, 0)
1st, Graph a boundary line > or < uses a dashed line ≥ or ≤ uses a solid line
Then, Test a point like (0, 0)

3. Ex 1: Graph
a) y ≥ 2
b) x > -1

4. Ex 2: Graph 4x + 2y ≥ 8

5. Only when in Slope-Int Form, you can use this shortcut:
> or ≥ means shade above the line
< or ≤ means shade below the line

6. Ex 3: Graph y < 3x - 4
