Find the co

Answer :

Let the P(a, b) and Q(c, d) divide the line segment AB in three equal parts.


Observation:


P divides AB in 1:2


Section formula


If a point P(x, y) divides a line segment joining A(x1, y1) and B(x2, y2) in a ratio m:n, then coordinates of P are



Hence, Coordinates of P:




Also, Q is the mid-point of PB


we know that, mid-point of line joining the points (x1, y1) and (x2, y2) is



Hence, coordinates of Q:



(c, d) = (–2, –5)
