Question

Find the y value for the point that divides the line segment CD into a ratio of 4:1.

Answer 1

We also drew a graph with 2 examples.

Explanation:

If we have the line segment CD, we can divide it by 4: 1 as follows:

If point C has the coordinates (x1, z1) and point D has the coordinates (x2, z2), we calculate coordinate the points Y as follows:

y1 = (x2-x1) · 4/5

y2 = (z2-z1) · 4/5

In this way we have obtained the point Y with the coordinates (y1, y2), and the point Y divides the line segment CD by 4:1.
