Refresher

The purpose of this section is to provide you with some resources to review in preparation for the lesson ahead. These resources may include videos, interactive applets, mini-lessons, and flash games to help you recall previously learned concepts. You can use these resources either before or after you try the questions in Are You Ready? Your teacher may also direct you to this section to review specific concepts.

Use the “Slope-Intercept Form: y = mx + b” video to review some of the concepts covered in Lesson 3.
Go to “Determining the Equation of a Line.”

---------------------------------------------------------------------------------------------------------------------------------

Use the “Graphing Linear Equations Using the Linear Function Explorer” interactive applet to review how the equation of a linear relation in slope-intercept form relates to its graph.

-------------------------------------------------------------------------------------------------------------

Lastly, go to “Formula” to review the definition of formula and how to rearrange formulas. In the Example section, you will see how the width variable in the perimeter formula can be isolated by balancing both sides of the formula. There is also a second example that shows how the radius variable in the circumference formula can be isolated.
