In ABC, AD and BE intersect each other at point Q. According to a theorem on medians, Q divides AD in the ratio 2 : 1. What are the coordinates of Q? A triangle has A equals (3, negative 2) (top), B equals (1, negative 5) (left bottom), C equals (7, negative 5) (right bottom), D and E are in the middle of the bottom and right sides. A point Q with an unknown value intersects between A D and B E.
