The graph represents this situation: Cara jogs every morning, and after minutes, she has run miles.

  1. How is Cara’s speed represented on the graph?

    The steepness of the line represents how fast Cara is going.

  2. Write a rule for Cara’s distance if represents the number of hours.

    How far does Cara travel each hour? How does the distance traveled each hour relate to the total distance run and the time spent running?

    d = 7t

  3. If Cara continues to run at this rate, predict how far she will run in hours.

    Use the answer from part (b) to help solve

A first quadrant linear graph:  x axis labeled, Time in hours, y axis labeled, Distance in miles. The line goes through the origin and the  point (1, comma 7). A slope triangle shows a 3.5, vertical rise, for a 1 half, horizontal run.
