Question

the line segment joining point M(5,7) and N(-3,2) is intersected by y axis at point L write down abscissa of L.h ence find the ratio in which l divide MN

Answer 1

M(5,7)≡(x1,y1)
N(-3,2)≡(x2,y2)
since the line segment is intersected by y axis 
therefore x=0
by using section formula for internal division
x=mx2 + nx1\m+n
0=m(-3)+n(5)\m+n
0*m+n= -3m+5n
0= -3m+5n
3m=5n
m/n=5/3
m:n=5:3
