A frog is presently located at the origin $(0, 0)$ in the xy-plane. It always jumps from a point with integer coordinates to a point with integer coordinates moving a distance of $5$ units in each jump. What is the minimum number of jumps required for the frog to go from $(0, 0)$ to $(0, 1)$?

If $P,Q,R$ are $\left(6,-1\right),\,\left(1,3\right),\,\left(x,8\right)$ respectively, then find the value of $x$ so that $PQ=QR$
