It is not a solution

Answer: No

- For (-1,2)

`\begin{gathered} 2(-1)-3(2)=-8 \\ -2-6=-8 \\ -8=-8 \\ \text{and} \\ 2=7(-1)+9 \\ 2=-7+9 \\ 2=2 \end{gathered}`

It is a solution

Answer: Yes

- For (2,0)

`\begin{gathered} 2(2)-3(0)=-8 \\ 4\\e-8 \end{gathered}`

It is not a solution

Answer: No

- For (5,6)

`\begin{gathered} 2(5)-3(6)=-8 \\ 10-18=-8 \\ -8=-8 \\ \text{and} \\ 6=7(5)+9 \\ 6=35+9 \\ 6\\e44 \end{gathered}`
