The given question is:


\begin{gathered} -11x-7y=-56 \\ -7y=-56+11x \\ y=(-56+11x)/(-7) \\ y=8-(11)/(7)x \end{gathered}

Put x as multiple of 7 to get ordered pairs as follows:


\begin{gathered} x=7,y=8-(11)/(7)(7)=8-11=-3 \\ x=14,y=8-(11)/(7)(14)=8-22=-14 \\ x=-7.y=8-(11)/(7)(-7)=8+11=19 \end{gathered}

So (7,-3);(14,-14);(-7,19) are ordered pairs. More can be calculated from the equation.
