Homework 6 (ref lect6) 20 points 1. In each case, find the parameters of the line y = mx + b that fit the data best from a least squares perspective. Show the work for computing the fit by hand, including finding the inverse of AT A. Notice that you can share some work between the two problems, since they have the same x values. Plotting your fits is optional, but a good way to check your work. 6*2 points 1. Points are (0,2), (1,3), (2,5). i1. Points are (0,6), (1,5), (2,1)
