Question

Find the ratio in which the join of (–4, 7) and (3, 0) is divided by the y-axis. Also, find the co-ordinates of the point of intersection.

Answer 1

`0 = (3k - 4)/(k + 1)`

3k = 4

`k = 4/3`   ...(1)

`y = (0 + 7)/(k + 1)`

`y = 7/(4/3 + 1)`   ...(From 1)

y = 3

Hence, the required is 4 : 3 and the required point is S(0, 3)
