The midpoint of AB is M(−5,−2). If the coordinates of A are (3,4), what are the coordinates of B?
+321 Okay this was a little bit hard doing in my head but if you have graph paper it comes in handy so I drew the coordinate plane and then just plot your points and you see point A is +8 apart from the midpoint (m) so knowing that point B is going to be -8 away from the midpoint which then makes the x coordinate of point B (-13,y) and then your Y would be the same as you point A so B = (-13,4)
