## Question

### Solution

Correct option is

5 : 7

The equation of the line passing through (6, 8) and (–3, –2) is ⇒  9y – 72 = 10x – 60

or  10x – 9y + 12 = 0                     … (i)

Let the required ratio be λ : 1.

Now the coordinates of the point P which divides the line segment joining the points (2, 3) and (4, 5) in the ratio λ : 1 is Clearly P lies on (i), then   ∴  The required ratio,  = –5 : 7

Hence the required ratio is 5 : 7 (externally).
