Find a vector perpendicular to the plane containing the given points.

(0,-2,2), (1,2,-3), and (4,0,-1)

My teacher was unable to finish the lesson, but I'd like to know how to solve this problem.

Use pairs of points to find two different direction vectors in the plane.
eg. (1,4,-5) and (4,2,-3)

Now take the cross product of those two vectors.
You should have learned an algorithm to do that.
