Question

Find the ratio in which the Y-axis divides the line segment joining the points (5, -6) and (-1,-4).

Answer 1

answer is 5 by dividing -x1/x2 because that is the formula if y-axis divides the line.if x-axis divides the line the formula is -y1/y2

Answer 2

heya friend,

let the point of intersection of y axis and the line joining the points (5,-6) & (-1,-4) Be P (X,Y)
since it's y axis therefore P(0,Y)

let the ratio be k:1
Using section formula we get the co-ordinate of P
P((5-k)/(k+1),(-6-4k)/(k+1))

as we know
(5-k)/(k+1)=0
5-k=0
k/1=5/1

therefore the ratio is 5:1

hope this helps
