Question

Write the ratio in which the line segment joining the points A (3, – 6), and B (5, 3) is divided by the y – axis?

Answer 1

Here the coordinates of the point A should be(-3,-6) and not (3,-6)
The coordinates of the point which is divided by the y-axis is (0,y)
0=(m1*x2+m2*x1)/(m1+m2)
0=m1*5-3*m2
3m2=5m1
(m1/m2)=3/5
So the ratio is 3:5
