Q12 of 77 Page 7


Find the ratio in which the line points (6, 4) and (1, - 7) is dividedinternally by the axis of x.

4: 7

SOLUTION:
Let the required ratio be k : 1. Then, the coordinates of the point of division are
But, it is a point on x-axis on which y-coordinate of every point is zero.
⇒ 7k - 4 = 0
Thus, the required ratio is k = 4 : 7.
