We first refresh what collinear vectors are. We then figure out what it takes for the components (or direction ratios) to make the vectors collinear. We then solve a problem applying the result. We then uncover what it takes for three points to be collinear. There are two methods for this one. Either prove that two vectors are collinear. Or prove that these three points can't form a triangle in space - which means that sum of side lengths (or magnitude) of two vectors is equal to the third.
