carthesian and parametric equation

(a) (2 points) Find the cartesian equation of the plane passing through Q = (1, 0, 2) and parallel to the plane 3:1: + 23; + z 3 = 0. (b) (3 points) Determine the parametric equation of the straight line perpendicular to the plane 1r: 3:1: + 23; + z 3 = D and passing through Q = (1,0,2). Compute the distance between the point Q and the plane 1r. ((3) (3 points) Let P1 = (0,0,0),P2 = (1,0, 2) and P3 = (0,3,0). Compute the area of the triangle with vertices P1, P2, P3
