1. 7-6 Inequalities

2. Steps to Graphing Systems
Solve both for y
Graph the lines y = mx + b (dashed if < or >)
Use a check point and shade in the correct direction
Highlight the double shaded region.

3. First get both equations solved for y.
Example
y > 3x + 1
4x + 2y < -4
-4x x
2y < -4x – 4
÷ ÷2
y < -2x – 2
First get both equations solved for y.

4. Next, graph the 1st line and shade
Example
y > 3x + 1
y < -2x - 2
Next, graph the 1st line and shade

5. Example
y > 3x + 1
y < -2x - 2
