Substitute point into Option A

\[

$$\begin{aligned} y + 7 &< 2x + 6 \\ 0 + 7 &< 2(0) + 6 \\ 7 &< 6 \quad (\text{False}) \end{aligned}$$

\]

Substitute point into Option B

\[

$$\begin{aligned} y - 7 &< 2x - 6 \\ 0 - 7 &< 2(0) - 6 \\ -7 &< -6 \quad (\text{True}) \end{aligned}$$

\]

Substitute point into Options C and D

\[

$$\begin{aligned} \text{Option C: } 0 - 6 &< 2(0) - 7 \implies -6 < -7 \quad (\text{False}) \\ \text{Option D: } 0 + 7 &< 2(0) - 6 \implies 7 < -6 \quad (\text{False}) \end{aligned}$$
