Substitute the values (x,y) for x and y in the equation and check if they satisfy the equation.
[tex](-1,5) \\
5 \times (-1)-2 \times 5=10 \\
-5-10=10 \\
-15=10 \\
not \ true \\ \\
(1,5) \\
5 \times 1-2 \times 5=10 \\
5-10=10 \\
-5=10 \\
not \ true[/tex]
[tex](0,-5) \\
5 \times 0 -2 \times (-5)=10 \\
0+10=10 \\ 10=10 \\
true \\ \\
(0,5) \\
5 \times 0 -2 \times 5=10 \\
0-10=10 \\
-10=10 \\
not \ true[/tex]
The answer is C.
