Big Idea Many real world situations can be modeled and predicted using mathematics.

Essential Question #2: What is the relationship between a table, a graph and an equation?

2.1

a. If Terry, Jade, and Jerome leave school together and walk toward the frozen yogurt shop at eh rates given in the table, how far apart will they be after 1 minute?

a. They are 60 meters away fro Terry and Jade and is is 30 meters away for Jade and Jerome.

b. If the yogurt shop is 750 meters from school, how long will it take each student to walk there?

b. It will take 12 minutes and 30 seconds for Terry. It takes Jade 6 minutes and 5 seconds. It will take Jerome 5 minutes.

c. When Jerome arrives at the yogurt shop, how far away will Terry be?

c. Terry will be 7 minutes and 30 seconds from Jerome.

2.1 follow-up

1. In problem 2.1, what strategies did you use to get your answers?

1. I figured out how to narrow down seconds into time and divide to narrow things.

2. Does problem 2.1 involve linear relationships? Explain why or why not.

2. Yes because you are comparing numbers on a scale of rates at different speeds.
