Question

Determine the ratio in which the line 2x + y - 40 divides the line woment joining the
points A(2,-2) and B(3.7).
in between and if the pointed
and 7
) are collinear​

Answer 1

Answer:

`3 : 4`

4:5

`5 : 7`

7:9

Answer :

C

Solution :

Let P( x, y) be the point of division that divides the line joining (3, -5) and (-4, 7) in the ratio of `k:1`

Now, `y=(7k-5)/(k+1)` ...(i)

Since, P lies on `y=0` or x-axis then, from eq. (i)

`0=(7k-5)/(k+1) implies 7k=5 implies k=5/7`
