1. The problem statement, all variables and given/known data (2 part problem) a) A plane passes through the point P(3,1,4) and is orthogona to the line (x-1)/2 = (2-y)/-7 = z-3 b) Find the point on the line closest to point (3,1,4) 2. Relevant equations Symmetric equation --> (x-x1)/t = (y-y1)/t = (z-z1)/t ( anyway i think that's what it is 3. The attempt at a solution I found the equation of the plane using the direction vector as (2,-7,1) and used this form 2(x-3)-7(y-1)+(z-4)= 0 I can't seem to be able to go on to start b. I would think of plugging P in but that seems way too easy. Any idea on how I can approach this?
