What if instead, for part 2., you had found the best-fit line t = C’ + Deb. Is the slope D related to the slope found in 1? How would you have expected the slopes to be related?

Exercise III (2 x 10 = 20 points)

1. Consider the data points (-2, 3), (2,1), (3, —4), and (5, 2). Find the equation of the best fit line b = C + Dt.
2. What if instead, for part 2., you had found the best-fit line t = C’ + Deb. Is the slope D related to the slope found in 1? How would you have expected the slopes to be related?
