Ch 11: SBA Math - Grade 8: Inequalities

About This Chapter

Viewing our fun video lessons on inequalities helps students prepare for related questions on the 8th grade SBA in math. Instructors teach students how to solve and/or graph a variety of problems, including inequalities involving systems, one or two variables, absolute values and more.

SBA Math - Grade 8: Inequalities - Chapter Summary

Before they take the 8th grade SBA in mathematics, your students can use our video lessons to review solving and graphing inequalities. These are important skills they'll need to feel confident answering certain kinds of questions on the examination. Once your 8th graders study this chapter, they will be able to do the following:

  • Graph 1- and 2-variable inequalities
  • Use set notation to describe compound inequalities
  • Graph inequalities and systems of inequalities
  • Solve and graph absolute value inequalities
  • Translate math sentences to inequalities
  • Solve one- and two-step inequalities

Our professional instructors simplify concepts and guide students through every stage of solving or graphing inequality problems. The videos contain several examples and graphics to help 8th graders grasp the material thoroughly, which will allow them to apply their knowledge of inequalities to more complex problems on the SBA.

What is an Inequality?

1. What is an Inequality?

Inequalities are equations that use greater- or less-than symbols and can be very helpful in situations that can have multiple solutions. Discover what an inequality is, understand what a two-variable inequality is, and learn how to graph two-variable inequalities.

How to Graph 1- and 2-Variable Inequalities

2. How to Graph 1- and 2-Variable Inequalities

Algebraic inequalities may be written as one-variable inequalities or two-variable inequalities and the number of variables affects the graphs of the inequalities. Investigate the differences between one-variable and two-variable inequalities and learn how to graph them on number lines and coordinate systems.

Set Notation, Compound Inequalities, and Systems of Inequalities

3. Set Notation, Compound Inequalities, and Systems of Inequalities

Compound inequalities are used to represent relationships of different algebraic expressions using inequality symbols. Learn about constructing and graphing compound inequalities, how to solve systems of inequalities, and how to represent these solutions in set notation and interval notation.

Graphing Inequalities: Practice Problems

4. Graphing Inequalities: Practice Problems

Algebraic inequalities are used to represent the relationship of two algebraic expressions by using inequality symbols. Investigate algebraic inequalities and learn how to graph them on the coordinate system using a series of practice problems in this lesson.

How to Solve and Graph an Absolute Value Inequality

5. How to Solve and Graph an Absolute Value Inequality

Inequalities and absolute value inequalities are graphed on number lines and coordinate systems, depending on the number of variables. Investigate inequalities and absolute value inequalities and learn how to solve and graph an absolute value inequality.

Solving and Graphing Absolute Value Inequalities: Practice Problems

6. Solving and Graphing Absolute Value Inequalities: Practice Problems

Absolute value inequalities can be classified into two types: an AND compound inequality or an OR compound inequality. Investigate the different types of absolute value inequalities, how to graph these inequalities, as well as solving systems of absolute value inequalities.

Translating Math Sentences to Inequalities

7. Translating Math Sentences to Inequalities

Watch this video lesson to learn how you can easily translate math sentences into inequalities. Once you know how to do this, solving word problems becomes that much easier.

How to Find the Distance Between Two Points

8. How to Find the Distance Between Two Points

After watching this video lesson, you will be able to find the distance between any two points on the coordinate plane. Learn what information you and how to plug them in to your formula.

Solving Two-Step Linear Inequalities

9. Solving Two-Step Linear Inequalities

After watching this video lesson, you will be able to solve any kind of linear inequality problem where you only have to perform two steps. You will know in what order to perform each step and you will know just what kind of operation you need to do.
