2. Inequalities

3. Example 1: Notice the open hole at the 5. This is because the inequality is greater than 5 but does not include 5. If it included 5, the hole would be filled in.

4. Example 2: You try! Write the inequality for this number line.

5. Example 2 Solution Now it is less than/equal to because the dot is filled in.
