Answer 2

Answer:

Step-by-step explanation:

co-ordinate of Y-AXIS are (0,Y)

let the ratio to be find out be K:1

applying midpoint formula; m1x2+m2x1/m1+m2

kx12+-1x3/K+1

0=12k-3

3=12k

k=1/4

so the ratio is 1/4:1

now applying mid point formula again,

Y=kx-3+1x6/K+1

Y=-3/4 + 6/5/4

Y=$\frac{21/4}{5/4\\}$

Y=21/5
