Lena [83]

Given: BO : OY = 5:8. Coordinate B is located at (4,2,) ; O is located at (57/8,-3) and Y is located at (x,y).

We have to determine the coordinate Y.

We will use cross section formula which states:

The coordinates $(x_1,y_1) , (x_2,y_2)$ are divided in the ratio $m_1 : m_2$ by the Coordinate A. So, the coordinates of A are given by the formula:
