Graphing and Writing Inequalities on a Number Line

This video tutorial by Mr. J provides an introduction to inequalities on a number line. It covers how to graph inequalities, offering a visual representation of solutions, and how to write inequalities from a number line. The tutorial includes examples to illustrate the concepts, such as using filled and open circles to indicate whether a number is included in the solution set. The video aims to enhance understanding of inequalities and their representation on number lines.

What does a filled circle on a number line represent?

• The number is positive

• The number is negative

• The number is included

• The number is not included
