2 2-5: Graphing Linear Inequalities
Definitions Inequality is an equation where the variable does not equal to each other >, <, or ≠ requires the dot being OPEN >, <, or = required the dot being CLOSED 11/30/2018 7:59 PM 2-5: Graphing Linear Inequalities

3 Steps for Solving and Graphing Absolute Value Inequalities
11/30/2018 Steps for Solving and Graphing Absolute Value Inequalities Identify whether it is an AND/OR inequality Write both equations with one with the regular sign and other equation with the sign SWITCHED with OPPOSITE number 11/30/2018 7:59 PM 2-8: Absolute Value Inequalities 3

4 Solving for Absolute Value Inequalities
11/30/2018 Solving for Absolute Value Inequalities When Solving for Inequalities, remember: Less ThAND GreatOR Than Less Than, “AND” Greater Than, “OR” 11/30/2018 7:59 PM 2-8: Absolute Value Inequalities 4
