The video tutorial covers solving and graphing inequalities, starting with a review of inequality symbols and their meanings. It explains how to represent inequalities on a number line using open and closed circles, as well as parentheses and brackets for interval notation. The tutorial includes examples of solving inequalities, demonstrating the process step-by-step, and concludes with additional resources for further practice.

What does an open circle on a number line represent?

• The number is included in the solution set.

• The solution set is empty.

• The number is not included in the solution set.

• The solution set is infinite.
