Question

Find the ratio in which the point P(3/4,5/12) divides the line segment joining the points A(1/2,3/2) and B(2,-5).

Answer 1

Answer:

Hi ,

We know that the section formula

_____________________________________________

The point which divide the line segment

joining the points A ( x1 , y1 ) , B ( x2 , y2 ) in the ratio k:1

is P ( kx2+ x1/k +1 , ky2 + y1 / k+ 1 )

______________________________________________

According to the given problem ,

A( x1 , y1 ) = ( 1/2 , 3 /2 )

B ( x2 , y2 ) = ( 2 , -5 )

P ( x , y ) = ( 3 / 4 , 5 / 12 )

Let the ratio = k : 1

x = 3/4 ( given

(kx2 + x1 ) / ( k+ 1 ) = x

( k× 2 + 1/2 ) / ( k + 1 ) = 3 / 4

2k + 1/2 = 3 /4 ( k + 1 )

4 ( 2k + 1 / 2) = 3 ( k + 1 )

8k + 2 = 3k + 3

8k - 3 k = 3 - 2

5k = 1

k = 1/5

Therefore ,

Required ratio = k : 1

= 1 /5 : 1

= 1 : 5

P divides the line segment joining the piints A and B

in the ratio 1 : 5

I hope this helps you.
