1-16.

Match each table of data below with the most appropriate graph and briefly explain why it matches the data.

  1. Boiling water cooling down. Homework Help ✎

    Time (min)

    Temp (˚C)

    Time will always be shown on the x-axis.

    Determine if the y-values are increasing or decreasing.

    Since the numbers for the y-axis are decreasing, the only graph which fits is Graph 3.

  2. Cost of a phone call.

    Time (min)

    .

    .

    Cost (cents)

    Are the y-values increasing at a constant rate?

    This could be Graph 1 or Graph 2, but the table would not contain the point (0, 0), so it must be Graph 2.

  3. Growth of a baby in the womb.

    Age (months)

    Length (inches)

    0.

    Identify the pattern of how the length increases.

    Graph 4 fits best.
