Graphing Absolute Value Equations and Inequalities on the Number Line

One of the most complicated situations in this unit is when you graph the solution to absolute value problems on a number line. The difficult part is that we often forget that there are often two situations that can make an absolute value problem true.

Solving equations involving absolute value signs are simpler to set up, for all you have to do is solve for the positive and negative value. When working with inequalities involving absolute value, you must remember to switch the direction of the inequality when solving for the negative value.

I would highly suggest reading Lesson 6.4, and paying particular attention to the summary box found on page 354.
