# Math Help - Plane problem..

1. ## Plane problem..

Hello again i need some help for this problem:

Find the plane equation if only is known that the point (3,4,-2) is normal projection of the coordinate start of that plane.

I presume that <3, 4, -2> is a vector, not a point.

What have you been able to do with this?

3. i'm sure that it is a point.. maybe the problem is set wrong... don't know

Another thought. What do you mean by "coordinate start of the plane?"

5. I mean the start - the beginning of that plane. (sorry the problem is not on english and i'm translating it)

6. Okay. Well we can solve the problem in the form it is in only if we have a vector that is going to be normal to the plane we are trying to find and we have a point on the plane. We have the normal vector, but we don't have the point.
