Suppose that the points (h, k), $\displaystyle (1,2)$ and ( $\displaystyle -3,4$ ) lie on the line $\displaystyle \mathrm{L}_1$. If a line $\displaystyle \mathrm{L}_2$ passing through the points $\displaystyle (\mathrm{h}, \mathrm{k})$ and $\displaystyle (4,3)$ is perpendicular to $\displaystyle \mathrm{L}_1$, then $\displaystyle \frac{\mathrm{k}}{\mathrm{h}}$ equals :
