# In what ratio is the line segment joining the points (– 2, – 3) and (3, 7) divided by the y-axis? Also, find the coordinates of the point of division.

Let the point on the y-axis which divides the line segment joining the points A(– 2, – 3) and B(3, 7) be C(0,y).

Let the ratio in which y-axis divides AB line segment be m:n.

Let (x,y) ≡ (0,y)

(x1,y1) ≡ (– 2, – 3)

and (x2,y2) ≡ (3,7)

Using Section Formula,  3m = 2n

m:n = 2:3

Now,  y = (5/5) = 1

Thus, the line segment joining the points (– 2, – 3) and (3, 7) divided by the y-axis in the ratio 2:3 internally and the coordinates of the point of division is (0,1).
