2 Express the following planes in vector form
(a) P1 ⊆ R3 with equation 4x - z = 0.
(b) P2 ⊆ R3 which passes through the points A = (-1,-1,0), B = (2, 3, 5), and C = (3,3,3).
(c) P3 ⊆ R3 with equation 4x - 3y + z = -10.
(d) P4 ⊆ R3 which is parallel to the yz-plane but passes through the point X = (1,-1,1).
(e) R2.
(f) P5 ⊆ R4 which passes through A = (1,-1, 1,-1), and where the coordinates of every point in P5 satisfy the equations x + y + 2z - w = 3 and x + y + z + w = 0.
