Answer:
The required sets of coordinates are (-4,28) and (-4,20).
Explanation:
Given information: A (-4, 16) and B (-4, 32).
Section formula:
If end point of a line segment are
and
and a point divides that line segment in m:n, then the coordinates of that point are

If a point divides AB in 3:1, then coordinates of that point are




If a point divides AB in 1:3, then coordinates of that point are




Therefore the required sets of coordinates are (-4,28) and (-4,20).
