Show that the mid-point of the line segment joining the points (5, 7) and (3, 9) is also the mid-point of the line segment joining the points (8, 6) and (0, 10).
Mid-point of the line segment joining the points (0,0) and (6,8) is
The mid point P of the line segment joining the points A (-10, 4) and B(-2, 0) lies on the line segment joining the points C (-9, -4) and D(-4, y). Find the ratio in which P divides CD. Also, find the values of y.
