 Question 158662: The Question is: Consider the line segment determined by A(-1,2) and B(5,11). Find the coordinates of a point P such that AP/PB=2/1. I have no idea where to start with this problem... My solution manual states that the point "must" lie 2/3 of the distance from A to B. My question is... How does someone find out that the point "must" be 2/3 the distance from A to B. I understand from the problem that line segment AP is twice as long as line segment PB. I found a midpoint (2,13/2) and the quarter point (7/2,35/4)and thought somehow I could come up with the 2/3 that they start with in the manual. Please explain how you get to the 2/3 distance.
