The Slope Formula!

Introduction

 

For my wonderful students who have the ability to conquer any task given to them:

Have you ever rode your bike down (or up) a hill?  How steep can the hill be before you have to stop and walk your bike the rest of the way up the hill.  How steep can the hill be before riding down becomes scary fast

Today you will learn how to find the slope of a line when only given two points from that line.  You already know how to find the slop using a graph!

Task

By the end of this webquest you will:

  • 1.  Know and be able to apply the slope formula.
  • 2.  Know how to find the slope of a line given any two points on that line.
  • 3.  Be able to identify positive, negative, zero, and undefined slope

Process

Part 1

  1. At the top of your own sheet of notebook paper, write "Webquest Vocabulary. Be sure to put your name on your paper.
  2. On your notebook paper, write the following vocabulary terms, leaving space between each word that will be defined as you complete the webquest:

               Words:  Slope; Positive Slope; Negative Slope; Zero Slope; Undefined Slope

*Ensure that I can read your information, or I can not give you credit for it.

Part 2

  1. You have the world wide web at the palm of your hand. So MANY resourse to use.
  2. Look up the vocabulary terms from Part 1.
  3. Write these definitions (in your own words) on your notebook paper.

Part 3

1.  Now go to one of the following website to watch a video detailing the slope formula

*(remember that it may take a few minutes for your video to load.  Please be patient)

*Feel free to take notes as you view the video. Rest assure...you will need to know this information.

 

Part 4

Complete page one of the worksheet titled finding Slope from Two Points

* note, page two will count as extra credit if you choose to complete this page.

 

Part 5

Turn in your vocabulary words and your worksheet into the basket when you have completed them for credit.

*You may turn these items in on Wednesday if you were unable to finish today.

Evaluation

The vocabulary words will be worth 3 points and the finding slope worksheet 1-8 will be worth 3 points.  You may complete 9-16 for three points of extra credit!

 

*Turn your papers in the the green turn in basket!!!

Conclusion

 

In this lesson you have learned how to determine slope given two points on a line.  You also have learned how to recognize the different types of slope.

Congrats on completing your Webquest! I knew you could do it!
