5. For each pair of planes, determine whether they are coincident, parallel and distinct, or intersect in a line. If the planes intersect in the line, determine a vector equation for the line of intersection. (a) (b) (c) T: 4x - 7y + 3z + 2 = 0 T: 2x+6y-3z + 2 = 0 [1: x+2y+3z-4 = 0 + 4 = 0 :-x-2y3z T: 3x + y2z + 6 = 0 1:2x+2y3z + 3 = 0 Justification for whether each pair of planes are coincident, parallel and distinct, or intersect in a line (3x 2 marks) I In any examples where the intersection is a line: Algebraic steps are clear for a reader regarding how a possible vector equation for the line of intersection was determined 16 14
