A plane is determined by three points or by two direction vectors and a point, now you've given one direction vector and two points, so you need to find another direction vector.

EDIT:

Do you want a vector equation or a cartesian equation? - Jul 26th 2011, 12:43 PMSironRe: Find the correct Plane!!
Does this help you? Or? ...

This is the way I would do it:

Given a plane and two points and the plane is parallel to a line who's direction ratios are . In general the vector equation of a plane through one point and with two directions vectors is: . Now we already have (we work now in a three dimensional space): . Can you determine the other direction vector ?

Ok :D, do you want to show me your solution?
