For certain ordered pairs $(a,b)\,$ of integers, the system of equations
\[\begin{aligned} ax+by&=3 \\ x^2 + y^2 &= 85  \end{aligned}\]has at least one solution, and each solution is an ordered pair $(x,y)\,$ of integers. In addition, ensure that $3a - 5b = 0$. How many such ordered pairs $(a,b)\,$ are there?
