  1. Usually Phil walks to school at a rate of 100 feet per minute.

    Complete the following table of values of the time in seconds and the distance in feet based on this rate.




  2. Sketch a graph of the following scenario.

    Phil's school is 1 500 feet from his house. Phil leaves home and walks about 300 feet for 3 minutes. He stops for 1 minute to talk with a neighbour out walking his dog. He continues to walk another 200 feet in 2 minutes. He stops at the corner store to grab a breakfast snack. This stop takes 2 minutes. Finally, Phil walks the remaining 1 500 feet to school in 10 minutes.



  3. A grade 10 student was asked to take fifty basketball shots. He took ten shots from each of the following distances to the hoop: 1 metre, 2 metres, 3 metres, 4 metres, and 5 metres.

    The table shows the results.



    1. Name the horizontal and vertical axes.

      Horizontal Axis: Distance, in metres
      Vertical Axis: Success rate as a percentage or Baskets made out of 10.

    2. State the ordered pairs of this relation.

      {(1,80), (2,70), (3,50), (4,60), (5,50)}
      or
      {(1,8), (2,7), (3,5), (4,6), (5,5)}

    3. Sketch the graph. Be sure to include appropriate labels.

      Two graphs are possible, depending on the information chosen for the vertical axis. A graph showing the success rate is shown.



    4. State a conclusion about the data presented in the graph.

      In general, the student's success rate decreased as his distance from the basketball hoop increased.
