Given:
A line segment AB.
A point is of the way from A to B.
To find:
The coordinates of that point.
Solution:
Section formula: If a point divide a line segment in m:n, then
From the given figure, it is clear that the two end points of the line segment are A(-4,-5) and B(12,4).
Let the unknown point be P. The point is of the way from A to B. It means,
Let AP and AB are 3x and 10x, then
It means, point P divided the line segment in 3:7.
Using section formula, we get
Therefore, the coordinates of the required point are (0.8, -2.3).
