Why do we take the ratio ad k:1
its rule...
Which one?
that if we not givem ratio we have to take k:1
ok byw
I am a little weak in coordinate geometry
OK thanks. It will be very helpful In my exams.
gud luck...
u can ask other questions too in afternoon i might find more helpfull for u
bye

Let the coordinates of the point be (0,y) and the y axis divide the line segment in the ratio k:1
(0,y)=[(-k+5)/k+1 , (-4k-6)/k+1]
=>0= -k+5/k+1
=>0= -k+5
=>k=5
Y= -4k-6/k+1
Y=4(5)-6/5+1
Y= -20-6/6
Y= -26/6
Y= -13/3
Thus the coordinates of the point is (0,-13/3)
Thanks!
