2.2+Changing+the+Walking+Rate

May 26-2009 Big Idea: Many real world situations can be modeled and predicted using math. Essential Q: What 8is the relationship between a table, graph and an equation?**
 * Andrew Raj**
 * Block C


 * Problem 2.2 & F.U**


 * A.Use the walking rates given in 2.1 to make a table showing the distance and time for Terry, Jade, and Jerome. How does the walking rate affect the data in the table?**




 * B. Graph the time and distance data for these three students. How does the walking rate affect the graphs?**


 * C. For each student, write an equation that gives the relationship between their time and distance walked. How does the walking rate affect the equation?**

C. The equations listed below are the equations that shows the relationship between each kids time and their walking rate:

Terry: d= t Jade d=2t Jerome: d=2.5t

Problem 2.2 F.U

1) We can say weather the data the data in data table will form a straight line on a graph when plotted is when the number is increasing by the same number each time.
 * 1) How can you use the information in the table to predict whether or not this data will lie on a straight line when graphed?**



2) A race which can create a shown above can be a walking race because at first the tables data shows that the that the person is trying to walk very fast and energetic but as the race comes to an end the person slows down because he or she was tired
 * 2) Describe the race that might have produced these data.**
