Question

For what ratio x-axis Divides the line (2,-5)and (1,9=

Answer 1

Step-by-step explanation:

let the ratio be k:1

By mid point formula

1+2/2; 9+-5/2

3/2;4/2

3/2;2=x

by section formula:

P(3/2,2)=k(1)+1(2)/k+1;k(9)+1(-5)/2

3/2=k+2/k+1

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

3k+3=2k+4

3k-2k=4-3

k=1

so the required ratio is k=1:1
