Asked by Lily
Determine the Cartesian equation of each of the following planes:
b) through the points (3,0,1) and (o,1,-1), and perpendicular to the plane with equation x-y-z+1=0
My teacher told me to find a direction vector, cross that with the normal, and set up my cartesian equation. I don't really understand why we do this though?
