(0,10,5) B.(2,6,2) C.(6,8,5) D.(0,0,-10) I had A as my answer and it was wrong. ---------------- x+3y-2z=20 A. (0,10,5) 0 + 3*10 - 2*5 =? 20 30 - 10 = 20 so A is on the plane. ---------------- B. (2,6,2) 2 + 3*6 - 2*2 =? 20 16 <> 20 B is not ------------------ C. (6,8,5) 6 + 3*8 - 2*5 =? 20 30 - 10 = 20 C is on the plane ------------ Check D
