Final answer:
The coordinates of the point that divides the directed segment from (-1,4) to (-9,0) in the ratio 1:3 are (-7,2).
Step-by-step explanation:
To find the coordinates of the point that divides the directed segment from (-1,4) to (-9,0) in the ratio 1:3, we can use the section formula. The section formula states that if a line segment AB is divided by a point P(x, y) in the ratio m:n, then the coordinates of P are given by:
x = (mx2 + nx1) / (m + n)
y = (my2 + ny1) / (m + n)
Plugging in the given values, we get:
x = (1(-9) + 3(-1)) / (1 + 3) = -7
y = (1(0) + 3(4)) / (1 + 3) = 2
Therefore, the point that divides the directed segment in the ratio 1:3 is (-7, 2).
