Ch 6: Geometry & Linear Equations

About This Chapter

This chapter on geometry and linear equations can help you improve your understanding of the midpoint formula, the distance formula, writing linear equations, and more. These lessons and quizzes are a great review for individuals preparing for an exam.

Geometry & Linear Equations - Chapter Summary

The lessons in this chapter provide an overview of geometry and linear equations. Some of the topics covered include the Cartesian coordinate system, the distance formula, and the point-slope formula. After completing the chapter, you should be prepared to:

  • Find the midpoint of a line segment
  • Identify the distance between any two points on a graph
  • Write a linear equation
  • Plot points and graph lines using the Cartesian coordinate system
  • Explain the point-slope form of an equation
  • Understand the relationship between x and y using the slope-intercept form of an equation

These video lessons are brief and engaging so that you can easily grasp the concepts presented. You can use the Help tab or your Dashboard to submit questions to instructors if you get stuck on a topic. A brief multiple-choice quiz is available for each lesson to test your knowledge.

How to Use The Midpoint Formula

1. How to Use The Midpoint Formula

The formula for the midpoint of a line segment will tell you how to find the middle of any line segment on the x, y plane. Learn about this formula and see how it is used to find the midpoint of a line segment.

How to Use The Distance Formula

2. How to Use The Distance Formula

You can't always rely on your smartphone to tell you how far you need to travel to get from point A to point B. The distance formula will tell you the distance between any two points on a graph. In this lesson, you'll learn where it comes from and how to use it!

How to Write a Linear Equation

3. 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.

The Cartesian Coordinate System: Plotting Points & Graphing Lines

4. The Cartesian Coordinate System: Plotting Points & Graphing Lines

Watch this video lesson to see how useful the Cartesian coordinate system is. Learn how points are labeled and how you can plot points and graph lines using the system.

Equation of a Line Using Point-Slope Formula

5. Equation of a Line Using Point-Slope Formula

It's time for a road trip to Las Vegas, and after four hours of driving at 60 mph ... Are we there yet? Learn the point-slope form of the equation of a line to help answer this age-old question.

Slope-Intercept Form: Definition & Examples

6. Slope-Intercept Form: Definition & Examples

The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.
