1. 1.8 Graphing Linear Inequalities
Objective: Graph linear inequalities

2. < , > → dashed lines < , > → solid lines
Linear Inequality:
A relation whose boundary is a straight line. It’s not a function because of the shading.
< , > → dashed lines
< , > → solid lines
1.) Graph the inequality as if it is an equation, then make line dashed or solid.
2.) Test a point in the inequality to see if you get a true or false statement.
3.) Shade whatever side gives a true statement.

3. Ex. 1) a.) Graph x < 2 b.) Graph x – 2y < 8
c.) Graph y < x + 1
See example 2 in book

4. Ex. 3.)
Graph -12 < 3x + y < 6
