25. For a given set of 4 data points, Ex = 2, Exy = 16, Ex² = 6, Ey 206. If the slope of the best fit line y = mx + b is 5, what is b? 8 None of the above. 26. Kathy needed to find the inverse of a 3 by 3 matrix A, so she started putting the augmented matrix [A7] into reduced form. She nearly finished the task, but had to catch a plane for Thanksgiving break. This is as far as she worked the problem: 0 0 1 lo o 10 -1 Assuming Kathy was correct to this point, find the (1,2) entry of A-1. -1 2 -1 1 2 -1 5 8 HI 3 25.
