Given:

The line segment of points A(-2, 0) and B(0, 8).

To Find:

The coordinates of the points divide the line segment into four equal parts.

Solution:

Let us consider P, Q and R are the points that divide the line segment into four equal parts.

A(-2, 0) and B(0, 8) where,

x₁ = -2, x₂ = 0, y₁ = 0, y₂ =8

For point P which divides line segment AB internally with a ratio of 1:3

where m =1 and n = 3.

Using the section formula, we know

P(x, y) = [(mx₂ + nx₁) / m+n, (my₂ + ny₁) / m+n]

         = [(1×0 +3×(-2)) / 1+3, (1×8 + 3×0) / 1+3]

         = (-6/4, 8/4])

         = (-3/2, 2)

For point Q which divides line segment AB internally with a ratio of 1:1

where m =1 and n = 1

Using the section formula, we know

Q(x, y) = [(mx₂ + nx₁) / m+n, (my₂ + ny₁) / m+n]

         = [(1×0 +1×(-2)) / 1+1, (1×8 + 1×0) / 1+1]

         = (-2/2, 8/2)

         = (-1, 4)

For point R which divides line segment AB internally with a ratio of 3:1

where m =3 and n = 1

Using the section formula, we know

R(x, y) = [(mx₂ + nx₁) / m+n, (my₂ + ny₁) / m+n]

         = [(3×0 +1×(-2)) / 3+1, (3×8 + 1×0) / 3+1]

         = (-2/4, 24/4)

         = (-1/2, 6)

Therefore, The coordinates of the point which divides the line segment into four equal parts are (-3/2, 2), (-1,4), and  (-1/2,6).
