Question

.
2. Find the ratio in which a straight lines 5x – 6y – 21 = 0 divides the line segment joining the points
(4, –) and (2, 1).

Answer 1

By mid point formula

(x2+x/2)(y2+y/2)

2+4/2;1+-1/2

6/2;0/2

3;0=P

P(x,y)=mx2+m2x/m+m2, my2+M2Y1/m+m2

P(3,0)=K(2)+1(4)/K+1,K(1)+1(-1)/K+1

P(3,0)=2K+4/K+1,K-1/K+1

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

3(K+1)=2K+4

3k+3=2k+4

3k-2k=4-3

k=1/1

k=1:1.........Answer
