. Find the ratio in which the y-axis divides the line segment joining the points
(5, –6) and (–1, –4). Also find the point of intersection.
Sol: Let the ratio be k : 1. Then by the section formula, the coordinates of the point which divides AB in the ratio k : 1 are
This point lies on the y-axis, \ its coordinates are (0, y)
So, k = 5
Thus, the ratio is 5 : 1.
