Answer:
39/7 , 61/7
Step-by-step explanation:
The coordinates of a point which divides the segment in the ratio 4 : 3 will be :-
[(4 × 9 + 3 × 1)÷(4 + 3)] , [(4 × 19 + 3 × -5)÷(4 + 3)]
= [(36 + 3)/7] , [(76 - 15)/7]
= 39/7 , 61/7

Answer:
by using section formula
x=mx2+nx1/m+n
=4×9+3×1/4+3
=36+3/7
=39/7
y=my2+ny1/m+n
=4×19+3×(-5)/4+3
=76-15/7
=61/7
:. the coordinates of the point which divides line in segment is (39/7,61/7)
