Answer 1

the ratio does y axis divides the line segment joining the points p(4,-6) and q(10,12) =6:12.

. The coordinate of the points intersection will be(13/12,0).

Let (x1,y1)=(4,-6) and(x2,y2)=(10,12).

slope= (y2-y1) (x2-x1)

=(12- -6) (10-4)

=-18/6

equation of the line pq- (y-5) (x- -4) =-18/6

...we get equation-- 12x+7y+13..

so, the ratio does y axis divides the line segment joining the points p(4,-6) and q(10,12).

Let(X,y) be the point in which divide a line in the ratio p:q.

.Let (X1,y1) and ( X2,y2) be the points and w=p+q.

point that divide the line in the ratio p:q is given by

x=X+p/w(x2-x1)

substituting we get p/w

and you will get the answer through this formula!!..
