To get from A (-4,3) to M (1,5) you must go 5 to the right and up 2.  Do that one more time and you will be at the other end of the diameter or go right 10 and up 4 from the original point and arrive at (6,7).

how do i show work????

mertsj · Answer

you could say m, the slope of AM = (3-5)/(-4-1)= -2/-5 = 2/5   Therefore the slope of MB must be the same so from Point M, if I rise 2 and run 5 I will be at (6.7)
