Linear Modeling 1. Some phone apps measure the number of steps taken during a period of time. John downloaded an app that reported data in a table like this: Time Steps Steps taken taken (minutes) 600 4000 20 2400 25 3000 4200 3000 35 2000 1000 10 20 30 40 Minutes (a) What are the variables of the problem? Identify independent and/or dependent variables of the problem if any. (b) Use the information from the table to graph the number of steps that John has taken over time. Connect the points on your graph. Does this curve or is it a line? (c) Explain why the graph tells you that John is walking at a constant pace.
