Question

Hi, I need help with this Linear Algebra problem, please. Thank you! :)

Suppose that the method of least squares is used to find the best-fit line through the following set of data points: (1,7), (3, 4), (5, 2), and (7, 1). In the notation of Section 6.3 in the workbook, let æ = (c, d)t be the solution to the system A* Ax = A*y. Given that a1 A* A = a2 az a4 find the value of the number aj . find the value of the number a2 find the value of the number a4 .
