Example 1: Write and Graph an Inequality Graphing Inequalities Hints:1. Always make sure the variable is on the left. (If you can say it, you can graph it. x>3 means x is greater than 3.)2. Put at least 5 numbers on your line. The number of importance and two on each side of it.3. Use open circles for > and <. Used closed circles for > and <.4. Make your directional arrows dark! :)

Example 4: Identify the Number of Solutions of an Inequality What to do when the variable "drops out"?
If the resulting inequality is TRUE, then the answer is ALL REAL NUMBERS. (There is an infinite number of possible values for the variable that will be true.)
If the resulting inequality is NOT TRUE, then the answer is NO SOLUTION. (There are no numbers that could make the inequality true.)
