Find the ratio in which y-axis divides the line segment joining the points $\displaystyle (5,-6)$ and $\displaystyle (-1, -4)$.
Marking-scheme solution
Let the point of division be \(\displaystyle \mathbf{P}(\mathbf{0}, \mathbf{y})\) which divides AB in the ratio K : $\displaystyle 1$
\[0=\frac{-K+5}{K+1} \Rightarrow K=5
\]
Ratio is $\displaystyle 5$:$\displaystyle 1$More from Coordinate Geometry
