Let 2 be the plane containing the line, l:(x,y,z)= t(6,4,2)+ (3,-4,2) and the point Q(5, -7, 7). Let P be the point (-6, -12,5)
a) Find the projection of QP onto 2.
I know the projection eqn would be (( plane 2 dot QP)/ magnitude on QP) * components of QP
The Attempt at a Solution
I got the vector QP to be (-11, -5,-2). I'm just confused on have to find the eqn of plane 2
