In what ratio the line segment joining the points (2, 3) and (4, 6) is divided by y-axis?
-
- Internally 1 : 2
- Externally 2 : 3
- Externally 2 : 1
- Externally 1 : 2
Correct Option: D
Let the co-ordinates of point be (0, y) because on y-axis, x is zero.
Let the ratio be k : 1
Using internal section formula, we get 
| 0 = | |
| k + 1 |
| k = | |
| 4 |
| k = | |
| 2 |
–ve sign shows that point divides the line segment externally.
