[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 $R=-<3.5,3>=$

Then the plane is $n\cdot R=0.$
