Question

e) In what ratio y-anis divide
the
join of (7,3) and (-5, -12)?​

Answer 1

Answer:

hii dude its easy ....

let A(7,3) and B(-5,-12)

According to question ...

also ,,, let P be point on y axis.. and P(0,x),, assume it

so..

by section formula,

P = [{ (-5k +7)/k+1 ,, (-12k +3)/k+1. }]

0,x = (-5k +7)/k+1 , (-12k + 3)/k+1

0 = -5k + 7 / k+1 ,,, x = -12k + 3 / k+1

0 = -5k + 7 ,,, let it be same

-7 = -5k

so .

value of k = 7/5.

so ratio is 7 : 5
