A blue and a red rubber band were stretched under different weights.
Here is a graph of the results with lines of best fit drawn.
  1. Which line do you think fits the data better? Why?

  2. What you can determine is the same for the two rubber bands? What can you say is different?

  3. Predict how much the red rubber band would stretch when 8 ounces of weight are attached? (Hint: it's not 7.)

  4. Write a NEXT/NOW equation for the red rubber band line. (Hint: it may help to make a table)
