Plug the values (x,y) into the equation and check if they satisfy the equation.

[tex](3,-2) \\ 2 \times 3 + 7 \times (-2)=8 \\ 6-14=8 \\ -8=8 \\ not \ true \\ \\ (2,-3) \\ 2 \times 2+7 \times (-3)=8 \\ 4-21=8 \\ -17=8 \\ not \ true[/tex]

[tex](-3,2) \\ 2 \times (-3)+7 \times 2=8 \\ -6+14=8 \\ 8=8 \\ true \\ \\ (0,4) \\ 2 \times 0+7 \times 4=8 \\ 0+28=8 \\ 28=8 \\ not \ true[/tex]

The answer is C.
