A fisherman has collected data about the length in inches, L, and weight in ounces, w, of fish he has caught.
The resulting line of best fit for the data is w=−37.1+3.2L

The predicted weight in ounces for a fish that is 22 inches long can be found by substituting L = 22 into the equation w = -37.1 + 3.2L:
w = -37.1 + 3.2(22)
w = -37.1 + 70.4
w = 33.3 ounces
Therefore, the predicted weight for a fish that is 22 inches long is 33.3 ounces.
Answer: 33.3 ounces
