Can anyone explain this to me
Q.4​

Answer 1

Answer:

let A and B are two points which have coordinates (3,5) and (-4,2).

There is a point between them which is y-axis have coordinates (0,y).

Then, according to section formula

x=mx2+nx1/m+n

Now, let (3,5) are (x1,y1) and (-4,2) are (x2,y2)

And (0,y) are (x,y).

0=-4m+3n/m+n

0= -4m+3n. ( m+n ×0= 0)

4m=3n

m/n=3/4

Finally, m:n=3:4
