Given a point $P(-4,3)$ on the terminal side of angle $α$, find the value of $\frac{\cos(\frac{π}{2}+α)\sin(-π-α)}{\cos(\frac{11π}{2}-α)\sin(\frac{9π}{2}+α)}$.
Given vectors $\overrightarrow{a}=(3,1)$ and $\overrightarrow{b}=(\sin α,\cos α)$, and $\overrightarrow{a}$ is parallel to $\overrightarrow{b}$, find the value of $\frac{4\sin α-2\cos α}{5\cos α+3\sin α}$.
