# Math Help - Parametric Plane Equation

1. ## Parametric Plane Equation

Find the parametric equations for the line through the point P = (0, 1, -3) that is perpendicular to the plane
Use "t" as your variable, t = 0 should correspond to P, and the velocity vector of the line should be the same as the standard normal vector of the plane.
x = ?
y = ?
z = ?

4. If $ax+by+cz+d=0$ is a plane then $$ is its normal vector.
