Question

Find the ratio in which (2, 7) divides the line joining the point (8, 9) and (- 7, 4).

Answer 1

Let A = (x1 y1) = (8, 9)

B = (x2 y2) = (-7, 4)

p = (x1 y2) = (2, 7)

The ratio l : m in which p divides AB, is given by

⇒ The ratio is l : m = 2 : 3

∴ the points (2, 7) divides internally
