Answer:

(4.75, 4)

Explanation:

We are to find the coordinates of the point that partitions the directed line segment AB in 1:3 ration.

For this, we will use the following formula:


x = x_1 + k(x_2 - x_1) ,
y = y_1 + k(y_2-y_1)

where
k is the ratio of the first segment to the whole line segment so in this case, it will
(1)/(4).

So substituting the given values in the above formula to find the coordinates:


x = 3 + \frac {1}{4} (10-3) = 4.75


y = 6 + (1)/(4) (-2-6) = 4

Therefore, the coordinates of the point that partitions the directed line segment AB in a 1:3 ratio are (4.75, 4).
