Question

Find the ratio in which p(4,m) divide the line segment joining the points A(2,3) B(6,-3) .hence find m

Answer 1

here is ur answer buddy.....

let the ratio be x:y

p(4,m)={(6x+2y)/x+y},{(-3x+3y)/x+y}

(6x+2y)/x+y=4
6x+2y=4x+4y
2x-2y=0
x:y=1:1

(-3x+3y)/x+y=m
-3+3=2m

2m=0
m=0

hope it helps......
