Parametric Plane Equation
Find the parametric equations for the line through the point P = (0, 1, -3) that is perpendicular to the plane https://webwork.math.lsu.edu/webwork...c0ae5b1b41.png
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 = ?

HINT: A line is perpendicular to a plane if it is parallel to the plane's normal.

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