2 Inequalities and their Graphs 763542 8

3 Objective: To write and graph simple inequalities with one variable

4 Inequalities and their Graphs 763542 8 What is a good definition for Inequality? An inequality is a statement that two expressions are not equal

5 Inequalities and their Graphs Terms you see and need to know to graph inequalities correctly Notice open circles < less than > greater than

6 Inequalities and their Graphs Terms you see and need to know to graph inequalities correctly Notice colored in circles ≤ less than or equal to ≥ greater than or equal to

7 Inequalities and their Graphs Let’s work a few together 3 Notice: when variable is on left side, sign shows direction of solution

8 Inequalities and their Graphs Let’s work a few together 7 Notice: when variable is on left side, sign shows direction of solution

9 Inequalities and their Graphs Let’s work a few together -2 Notice: when variable is on left side, sign shows direction of solution Color in circle

10 Inequalities and their Graphs Let’s work a few together 8 Notice: when variable is on left side, sign shows direction of solution
