For example:

[tex]P_1[/tex] = 4x-2y+6z=3 and [tex]P_2[/tex] = -6x+3y-9z=4

then [tex]\vec{n}P_1[/tex] = <4,-2,6> and [tex]\vec{n}P_2[/tex] = <-6,3,-9>. So, my thinking is that if these two planes were || then they should have the same normal vector or at least a multiple of that normal vector. Is this correct, should I be looking at something else as well?
