Let P(5, -6) and Q(-1, -4) be the given points.

Let y-axis divide PQ in the ratio k:1

Then, the coordinates of the point of division are

Since, R lies on y-axis and x-coordinates of every point on y-axis is zero

Hence, the required ratio is 5 :1

Putting k=5 in the coordinates of R, we get

Hence, the coordinates of the point of division are
