1. The problem statement, all variables and given/known data Find an equation of the set of all points equidistant from the points A(-1,5,3) and B(6,2,-2). Describe the set. 2. Relevant equations None... 3. The attempt at a solution Um, I've drawn a graph of the two points and that's about as far as I could get. I know the answer should be a plane going between the two points... but how do I find the equation?
