1. The problem statement, all variables and given/known data Find the equation of the plane that goes through points P, Q and R. P = (3, -1, 2), Q = (8, 2, 4) and R = (-1, -2, -3) 2. Relevant equations Eq of plane 0 = a(x - x0) + b(y - y0) + c(z - z0) 3. The attempt at a solution In order to find vector normal to the plane, my teacher took the cross product of PQ X PR. Would I still get the correct normal vector if I take the cross product of PQ X QR? Finally, when I plug in the numbers to the equation in "2. Relevant equations", does it matter which point I choose (P, Q or R) for x0, y0, or z0? Thank you.
