Question

Find the co-ordinates of the point which divides the line segment joining the points (4, – 3) and (8, 5) in the ratio 3 : 1 internally.

Answer 1

Let P(x, y) be the required point Here (x₁ = 4, y₁ = – 3) and (x₂ = 8, y₂ = 5) and m₁ = 3, m₂ = 1

By section formula, we have

Hence, co-ordinates of required point, are (7, 3).
