Extracted text: Let L, be the line given by the intersection of two planes 2x- y+z = 1 and x – y = -2 and let L2 be the line given by parametric equation x = 2 – t L2 : y = 3 – 5t z = t If u denotes the direction vector of L1 and uz denotes the direction vector of L2. Then (a) Find the vectors u and uz. (b) Find the dot product of the vectors u and u2. (c) Find the cross product of the vectors u and u2.
