Given:
[tex]-8x+y=8[/tex]When x=0,
[tex]y=8[/tex]When x=3,
[tex]\begin{gathered} -8(3)+y=8 \\ -24+y=8 \\ y=32 \end{gathered}[/tex]When y=0,
[tex]\begin{gathered} -8x+0=8 \\ -8x=8 \\ x=-1 \end{gathered}[/tex]Final answers are
[tex]\begin{gathered} x=0,y=8;(0,8)\text{ } \\ x=3,y=32;;(3,32) \\ x=-1,y=0;;(-1,0) \end{gathered}[/tex]
