The correct answer is:
$(-1,-1)$ and $(3,7)$
$\begin{aligned}
& L_{(-1,-1)}=3(-1)-8(-1)-7 \lt 0 \\
& L_{(3,7)}=3 \times 3-8 \times 7-7 \lt 0
\end{aligned}$
Hence $(-1,-1)$ and $(3,7)$ lie on the same side of line.
& L_{(-1,-1)}=3(-1)-8(-1)-7 \lt 0 \\
& L_{(3,7)}=3 \times 3-8 \times 7-7 \lt 0
\end{aligned}$
Hence $(-1,-1)$ and $(3,7)$ lie on the same side of line.
