Ch 10: Praxis Mathematics: Linear Equations

About This Chapter

We can help you learn to work with linear equations. Through video lessons and self-assessment quizzes you will get instruction and practice solving problems that will prepare you for questions on the Praxis Mathematics test.

Praxis Mathematics: Linear Equations - Chapter Summary

This chapter's lessons will help you understand linear equations. You'll learn about lines as models for growth, the definition of a linear equation and how to solve linear equations. Several lessons consist of practice problems that let you test your skills. Here are some of the topics covered in the videos that will help you prepare for the exam:

  • Interpreting the coefficients of a linear equation in context
  • Intercepts, standard form and graphing
  • Applying the distributive property to linear equations
  • Interpreting the slope and intercept of a linear model
  • Using graphs, points or description to find the equation of a line
  • Finding the slope and intercepts of a line
  • Understanding real world linear growth

Experienced instructors lead you through the lessons, helping you master each concept as you get ready to take the exam. As you build your knowledge of linear equations, you'll find that you enjoy learning with these videos.

Objectives of the Praxis Mathematics: Linear Equations Course

Many states require that secondary school teachers pass subject area Praxis exams in the areas in which they are seeking certification. The Praxis Mathematics exam consists of 50 questions, and you will have two hours to complete it. The questions on linear equations are found in the data analysis probability section of the Praxis Mathematics exam. This section has five or six questions that make up between 10-12% of the test's total of 50 questions.

All questions on the Praxis Mathematics test are multiple-choice. You will be presented with a problem and four possible answers. The self-assessment quizzes at the end of each video lesson will help you prepare for the test by becoming familiar with the format, in addition to checking your knowledge.

What is a Linear Equation?

1. What is a Linear Equation?

Most cars won't be able to run for more than 250,000 miles, so how much longer will your car live? Linear Equations are the most basic kind of algebraic function and can help you answer questions exactly like this. Learn about what they look like, how they come up in your life and why they are powerful tools.

How to Write a Linear Equation

2. How to Write a Linear Equation

Simply knowing how to take a linear equation and graph it is only half of the battle. You should also be able to come up with the equation if you're given the right information.

Problem solving using Linear Equations

3. Problem solving using Linear Equations

From sale prices to trip distances, many real life problems can be solved using linear equations. In this lesson, we'll practice translating word problems into linear equations, then solving the problems.

Solving Linear Equations: Practice Problems

4. Solving Linear Equations: Practice Problems

With practice, linear equations can be straightforward to solve. In this lesson, we'll define linear equations and learn how to solve them. We'll look at multiple practice problems and walk through solving each one.

Linear Equations: Intercepts, Standard Form and Graphing

5. Linear Equations: Intercepts, Standard Form and Graphing

Do you know what to do if an equation doesn't look like y=mx+b?! If not, then this video is for you. Chances are the equation is in standard form, so we'll learn how to use standard form equations, how to graph them and why they can be helpful.

Applying the Distributive Property to Linear Equations

6. Applying the Distributive Property to Linear Equations

When it comes to linear equations, there are certain steps you have to take to solve them. One of them is the application of the distributive property when you see a pair of parentheses. Watch this video lesson to learn how.

Solving Linear Equations with Literal Coefficients

7. Solving Linear Equations with Literal Coefficients

In this lesson, we'll literally learn about literal coefficients. We'll look at how to solve linear equations that contain literal coefficients and practice solving several problems.

How to Find and Apply The Slope of a Line

8. How to Find and Apply The Slope of a Line

In this lesson, we'll discover all about the slopes of lines. We'll learn about different types of slopes and how to find the slopes of lines. We'll use two methods: the slope formula and the slope-intercept form.

How to Find and Apply the Intercepts of a Line

9. How to Find and Apply the Intercepts of a Line

How can you take an equation of a line and find out where it will cross the x- or y-axis? In this lesson, we'll define x-intercepts and y-intercepts and learn how to find them.
