Line A: y = 3 0.6x, Line B: y = 4 x Data points: We have presented

Line A: y = 3 ˆ’ 0.6x, Line B: y = 4 ˆ’ x
Data points:

We have presented two linear equations and a set of data points. For each exercise,
a. Plot the data points and the first linear equation on one graph and the data points and the second linear equation on another.
b. Construct tables for x, y, ^y, e, and e2 like Table 14.4 (page 626).
c. Determine which line fits the set of data points better, according to the least-squares criterion.
