(9pts) Assume that you are fitting a linear function p to pass through two points (21, y1) and (12, 12), where you form an augmented matrix to find the a and b such that p(x) = a + br and p(x1 ) = 1 and p(x2) = 1/2. (a) (3pts) If the two points were (2, 4) and (2, 6), then a unique solution would exist for this linear system (circle one) True / False (b) (3pts) If the two points were (4, 2) and (6, 2), then a unique solution would exist for this linear system (circle one) True / False (c) (3pts) If the two points were (4, 2) and (8, 0), then a unique solution would exist for this linear system (circle one) True / False
