Question

find the ratio in which the line joining (3,4) and (-2,1) is divided by the y-axis

Answer 1

The ratio in which the line joining $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is divided by the y-axis is $(-x_{1} : x_{2})$

$(x_{1},y_{1}) = (3,4) \\ (x_{2},y_{2}) = (-2,1)$

The required ratio = $\frac{-3}{-2}$
= 3 : 2
