Project+Description

What’s in a Line?

Linear relationships are used to represent real life relationships that demonstrate a constant rate of change. Linear relationships can be used to create linear equations that will allow you to make predictions. We have studied linear relationships and linear equations including the slope intercept form of a linear equation, y = mx +b. In this project you will be using this knowledge to explore real life linear relationships and create your own linear equations and graphs.

The Assignment

You will investigate all three of the real world linear relationships below and then choose one to present upon. The categories are comparing cell phone plans, burning calories, and statistics from the NBA or WNBA. You will gather data on your subject, write an equation, and create a graph representing your data. Then you will present your findings to the entire class.

The Steps

1. Look at the following three real-life situations


 * 1) Buying a Cell Phone
 * 2) Burning Calories
 * 3) NBA or WNBA Statistics

2. Depending on what you chose click on the links below to get started on your project.
 * 1) [|__Burning Calories Worksheet__]
 * 2) [|__Buying a Cell Phone__]
 * 3) [|__Basketball Statistics Worksheet__]

3. Go to one of these linked sites to investigate your topic:
 * 1) [|Burning Calories]
 * 2) [|__Buying a Cell Phone__]
 * 3) [|__NBA Statistics__]
 * 4) [|__WNBA Statistics__]

4. Using the data you find complete the worksheet for the topic you have chosen. The worksheets must be completed by everyone individually.

5. Using your data, create a linear graph.

6. For one of the three topics, prepare a brief oral report to give to the class, in this report you will:

1. Explain your graph including what the y-intercept, slope, and equation for your graph are. 2. Share what information can be learned from your graph and make a prediction based on this information. 3. Share at least one way this information could be used in daily life. 4. See grading rubric for grading details.
