1. The problem statement, all variables and given/known data Find the equation of the plane through vectors u=(1,1,2) parallel to the plane containing v=(2,2,-1), w=(1,-1,0), and the origin. 2. Relevant equations 3. The attempt at a solution I did the cross product of v x w = (-1,-1,-4). Thus, my equation became -x-y-4z=-9. Is this correct? Thanks.
