Find the ratio in which the line segment joining the points A (3, – 3) and B (– 2, 7) is divided by x-axis. Also find the coordinates of the point of division.

Let the point C (x, 0) divide the line segment A (3, – 3) and B (– 2, 7) in the ratio k : 1


The co-ordinates of C is given by,





Now, according to the given figure,



⸫


⇒ 7k – 3 = 0


⸫ k =


⸫ The ratio = k : 1 = : 1 = 3 : 7
