Q21 of 157 Page 760

In what ratio does the x-axis divide the join of A(2, -3) and B(5, 6)?

⇒ Let the ratio be k:1.


⇒ Then by section formula the coordinates of point which divide the line AB is given as



⇒ Since the point lies on x-axis its y-coordinate is zero.


⇒ = 0


⇒ 6k = 3


⇒ k = 1/2


Therefore the ratio in which x-axis divide the line AB is 1:2.
