If O(0,4) and P(0,−4), are the coordinates of the line segment OP then co-ordinate of its midpoint is
M is the mid-point of the line segment joining the points A(0, 4) and B(6, 0). M also divides the line segment OP in the ratio 1 : 3.Find: (i) co-ordinates of M (ii) co-ordinates of P (iii) length of BP
