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.
