Answer:
A and B
Explanation:
If point P (x,y) lies on line segment
(between points A and B) and satisfies AP:PB=m:n, then we say that P divides
internally in the ratio m:n. The point of division has the coordinates
CORRECT
- Line segment AB has endpoints A(5, 4) and B(2,7). The coordinates (4,5) divides the line segment directed from A to B in the ratio of 1:2

- Line segment AB has endpoints A(6,5) and B(3,8). The coordinates (5,6) divides the line segment directed from A to B in the ratio of 1:2.

INCORRECT
- Line segment AB has endpoints A(5,7) and B(8,4). The coordinates (6,5) divides the line segment directed from A to B in the ratio of 1:2.

- Line segment AB has endpoints A(7, 2) and B(4,8). The coordinates (5, 4) divides the line segment directed from A to B in the ratio of 1:2.

REMARK
A and B are correct. However the coordinates of P for C and D are incorrect.
