If R divides the line segment joining P(2,3,4) and Q(4,5,6) in the ratio −3:2, then the value of the parameter which represents R is?
If P (9a-2, -b) divides the line segment joining A (3a+1, -3) and B( 8a, 5) in the ratio 3:1, find the value of a. a = ___.
The ratio in which the point R (1, 2) divides the line segment joining points P (2, 3) and Q (3, 5) is:
