a) b) Consider the plane and the line with these equations: [6 marks] 0 = 4x - 2yz + 12 7 (3,4, a) + t(7, b, 6) = :. a must Find all the values of a and b such that the plane and the line intersect at every point on the line. c) and b must Find all the values of a and b such that the plane and the line will always intersect at a single point. Explain. :: a must and b must Find all the values of a and b such that the plane and the line will not intersect. Explain. I L ju 3
