Graphing Inequalities on a Number Line

The video tutorial covers graphing inequalities on a number line. It begins with an introduction to inequalities and their symbols, explaining the difference between open and closed circles. The tutorial then demonstrates graphing the inequality 2 < x, showing how to determine the direction of shading. Another example, x ≤ -3, is graphed with a closed circle, illustrating the inclusion of the endpoint. The lesson concludes with a recap of the steps for graphing inequalities, emphasizing the importance of identifying the correct circle type and shading direction.

What is an inequality?

• A relationship between two variables

• A relationship between two expressions that are not equal

• A relationship between two equal expressions

• A relationship between two numbers

In the inequality 2 < x, why is the circle at 2 open?

• Because 2 is included in the solution

• Because 2 is equal to x

• Because 2 is not included in the solution

• Because 2 is greater than x
