Extracted text: 2. Given the set of data points {(-3, -1), (-2, 1), (0, 2), (1, 3), (3, 2)}, fit a straight line y = mx + b that approximates the points in the least-squares sense. 1. Write a least-squares system Ax = b which can be used to obtain values for m and b. 2. Solve the obtained system above using the method of normal equations
