1. Algebra I Section 5-6 Graphing Inequalities in Two Variables

2. Review: Graph the equation using slope-intercept form. 

3. Graphing Linear Inequalities  Step 1: Rewrite the equation so y is by itself  Step 2: Write down the slope and the y-intercept  Step 3: Plot the y-intercept (the “b” value)  Step 4: “Move” up/down the slope from that point

4. Graphing Linear Inequalities (continued) 

5.  Step 6: Test a point to determine which side of the line should be shaded  If the test point is true, then shade the side that does include the test point  If the test point is false, then shade the side that does not include the test point

6. Graph each inequality. List the m and b, and say whether it is a dashed or solid line. Then graph and shade. 
