In what ratio is the line joining A(0, 3) and B (4, -1) divided by the x-axis ? Write the co-ordinates of the point where AB intersects the x-axis.

Let AB intersect x-axis at P. So, co-ordinates of P = (x, 0). Let ratio be m 1 : m 2 . By section formula, m 1 : m 2 = 3 : 1. P = (x, 0) = (3, 0). Hence, co-ordinates of P = (3, 0) and ratio = 3 : 1.
