For each of the following collections of 3D vectors, describe their span (is it a line, a plane, all of Ro, or just the origin?). If the span is a line, give a parameterization which describes it. If the span is a plane, give an equation which describes it. a. 01 = b. 71 = 1 . 53 - [8] . 3- [ 2 -6 C. 71 = -4 U2 = -2 12 6 3 -18 d. 71 = -2 = Cn 0 e. D = -2
