The unit vector that has the same direction as the vector from the point A=(2,2) to the point B=(4,0) is? I chose to find the length so that would be A-B right? I got (-2,2) as the vector between the two points. I found its magnitude which was 2, then I divided the vector <-2,2> so it'll be a unit vector. My answer was <-1,1> but I'm wrong.
