distance from POINT to PLANE

Another one....(Headbang)

Point (P): **(2,3,-1)**

Plane: **2x + y - 2z + 9 = 0**

1. Determine equation of line L, perpindicular to the plane and passing through point P.

2. Determine Point A (where L and plane intersect).

3. Distance from A to P (Point)

4. Also- How would you find the distance from the point using a VECTOR PROJECTION.

5. Knowing that- Find the distance from Point P (-4, 7, -3) to the plane which is 3x + 2y - 5z + 11 = 0.

P.s.- Plato similar type of question but a little different thus giving me some issues.

Thanks a lot!
