In your last lesson you researched and began to analyze linear data. This data may have been related to the Olympics. In this lesson you will use the same data that you already have: a table of values, a graph, or an equation. You will use that information to answer questions.

Go to the Unit 3 Project and complete the Module 5: Lesson 2 component of the project.

There are many factors to consider when you are planning to buy a new car. These include safety, comfort, style, handling, and fuel consumption. For many people, fuel consumption is one of the most important factors. Graphs of linear functions can be used to assist consumers in their vehicle purchases.

Study the following graph, which compares the fuel consumption of a Smart car to that of a Volvo.

This shows a graph of the fuel consumption of a Smart car compared to the fuel consumption of a Volvo.

Notice the information you can gain from looking at the intercepts on the graph.

  1. What title would you give to this graph?

  2. Do you think you could find the equation of the green line (the Volvo) and the red line (the Smart car)?

  3. What do you think the slopes of the blue line and the green line represent?
