1. The problem statement, all variables and given/known data Given a + b + c = 7, find a, b and c such that the point (a,b,c) lies on the line passing through the points (3,-4,0) and (2,-2,3) a = b = c = 2. Relevant equations None 3. The attempt at a solution My instructor didn't go through this portion and I was wondering if I could get a little help. The way I understand the question is that there is a point between (3,-4,0) and (2,-2,3), such that they equal 7. I'm not sure how to go about this question. Any hints? Thanks in advance.
