Graphing Inequalities on a Number Line

The video tutorial explains how to graph inequalities on a number line. It introduces the concept of inequalities, discusses the different inequality signs, and demonstrates how to graph each type using the number 2 as an example. The tutorial covers graphing x equals 2, x less than or equal to 2, x less than 2, x greater than or equal to 2, and x greater than 2. It also explains the importance of open and closed circles in graphing and concludes with a discussion on variable positions in inequalities.

What is the main objective of the lesson on graphing inequalities?

• To learn about functions

• To graph the set of solutions to an inequality

• To solve equations

• To understand algebraic expressions
