Use the graph below to add points to the table below.

For each point, find its -coordinate and its -coordinate and record the two numbers next to each other in the table.

  1. Write the rule in words.

    Notice that for every the -value increases, the -coordinate decreases by . Also take into account where the -intercept is.

    Multiply by and then add .

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

    Extend the pattern in the table. Answers may vary.
