this is from my 'distance from a point to a plane' lesson. pls help. if you can write on paper answer, that's apreicated.

Question 1. Points A(1,2,3), B(-3,-1,2) and C(13,4,-1) all line on a plane. Determine the distance from the point P(1,-1,1) to this plane.

Question 2. Two planes with the equation x-y+2z=2 and x+y-z =-2 intersect along the line L. Determine the distance from the point P(-1,2,-1) to the line L and determine the coordinates of the point on the line L that gives the minimum distance.

Thank you so much.
