Determine whether the following planes below are parallel, perpendicular, or neither.

---

choose one Parallel Perpendicular Neither 1. $x+2y-6z=0$ and $-3 x-6 y +18 z = -3$.

choose one Parallel Perpendicular Neither 2. $x-3y+z=0$ and $-x-4 y +z = 5$.

choose one Parallel Perpendicular Neither 3. $x+8 z=0$ and $8 x- z = -3$.
