An engineer wants to determine the spring constant for a particular spring. She hangs various weights on one end of the spring and measures the length of the spring each time. A scatterplot of length (y) versus load (x) is depicted in the following figure.

a. Is the model y = ?₀ + ?_1x an empirical model or a physical law?

b. Should she transform the variables to try to make the relationship more linear, or would it be better to redo the experiment? Explain.
