4. Show that the YZ-plane divides the line segment joining the points (3, 5, -7) and (-2, 1, 8) in the ratio3; 2 at the point (0, 13/5, 2).
5.Show that the ratios in which the coordinate planes divide the join of the points (-2, 4, 7) and (3, -5, 8) are 2: 3, 4: 5 (internally) and 7:8 (externally).
6. Find the coordinates of a point R which divides the line segment P (x, y, z) and Q (x, y, z) externally in the ratio. Verify that Q is the mid-point of PR.
