    [SOLVED] Lines and Planes?

    It says, Find the equation of the plane in xyz-space through the point P = (3, 5, 3) and perpendicular to the vector n = (-5, -5, -4). Can someone show me, step by step how to work this problem out or explain to me what I'm doing? I'm so lost.

    Let R=<x,y,z>-<3.5,3>=<x-3,y-5,z-3>

    Then the plane is n\cdot R=0.
