Question

the ratio in which the point 1,2 divide the line joining the point -1, k1 and 2, K2 is

Answer 1

let the ratio be m:1
now by the section formulae


(mx2 + nx1)/m+n = 1



(2m - 1)/m+1. = 1

2m - 1 = m+1

m = 2
therefore the ratio is 2:1

Answer 2

let the ratio be m:1

now by the section formulae

(mx2 + nx1)/m+n = 1

(2m - 1)/m+1. = 1

2m - 1 = m+1

m = 2
therefore the ratio is 2:1
