MISS ZEUGGINNOVEMBER 5TH 2008
OBJECTIVES: GRAPH A LINEAR INEQUALITY IN TWO
VARIABLES
Standards: 2.5, 2.8
CHAPTER 6 SECTION 5Graphing Linear In equalities in Two Variables
Inequality Review
Graph the following Inequalities
Examples:
4x 0x3x 2x
Checking Solutions of a Linear Inequality Is (0,0) a solution of ?
Is (2,-1) a solution of
4 yx
32 yx
Graphing Inequalities
STEPS: Rewrite equation in slope-intercept form
y=mx+b Graph the equation Choose a point to check Shade in the correct area
< or > is a dotted line ≤ or ≥ is a solid line
Examples
1. Graph the inequality
Step 1:
Graph
Check: Point (-3,0)
Shade:
42 yx
42 xy
Examples:
2. 3. 3 yx 6 yx
Examples:
