The coordinates of point R that divides the line segment joining points P (x1, y1, z1)
and Q (x2, y2, z2) in the ratio m: n are
Point A( 3, 2, 5 ) and B( -4, 2, -2 ), m and n are 4 and 3 respectively.
Using the above formula, we get,
( -1,2,1), is the point which divides the two points in ratio 4 : 3.
