Use the graph shown at right to enter the ordered pairs in the table below.

  1. Write the rule in words.

    Write the coordinates of the corresponding points from the graph at right. Two points have been filled in for you.

    Remember, try to find the rule based on the constant given by the -value when is .
    Then work backwards and see how and are related after working in the constant.

    Multiply the number by three and then subtract by four.

  1. Explain how to use the table to predict the value of when is .

    If for every value of , the -value increases or decreases by , how can you compare and ?
