Homework Help: Easy calc 3 question: points on a plane

  1. Sep 17, 2005 #1
    The question asks:
    Which of the points P(3,2,1), Q(2,3,1),R(1,4,1) lie on the plane

    I know this is a pretty easy problem...but I am drawing a blank on where to start? Should I form vectors from each point ? If so, then what?

    A little lost!

    If the point lies on the plane, then it is a solution to the equation.
