Answer 2

Answer:

Let the point be A(5,−6), B(−1,−4) and P(0,y)

Point P is on y−axis,hence its x co-ordinate is 0.So, it is of the form P(0,y)

Now, we have to find ratio.

Let the ratio be k:1

Hence m

=k, m

=−1,y

=−4, x=0, y=0

Using sections formula x=

−k+5

∴k=5

Again y=

−20−6

for k=5

−13

Hence the cordiantes of point is P(0)
