Plug the values into the equation and check if it's true.

[tex](x,y)=(-9,-12) \\ 4 \times (-9) -5 \times (-12) \stackrel{?}{=} 24 \\ -36+60 \stackrel{?}{=} 24 \\ 24 \stackrel{?}{=} 24 \\ 24 = 24 \\ a \ solution \\ \\ (x,y)=(1,-4) \\ 4 \times 1 - 5 \times (-4) \stackrel{?}{=} 24 \\ 4+20 \stackrel{?}{=} 24 \\ 24 \stackrel{?}{=} 24 \\ 24=24 \\ a \ solution[/tex]

[tex](x,y)=(4,8) \\ 4 \times 4 - 5 \times 8 \stackrel{?}{=} 24 \\ 16-40 \stackrel{?}{=} 24 \\ -24 \stackrel{?}{=} 24 \\ -24 \not= 24 \\ not \ a \ solution \\ \\ (x,y)=(6,0) \\ 4 \times 6- 5 \times 0 \stackrel{?}{=} 24 \\ 24 -0 \stackrel{?}{=} 24 \\ 24 \stackrel{?}{=} 24 \\ 24=24 \\ a \ solution[/tex]

The answers are A, B and D.
