The correct answer is option A.

Step-by-step explanation:


\begin{gathered} -13\ge r+7 \\ \text{Subtract 7 from both sides, we get} \\ -13-7\ge r+7-7 \\ -20\ge r \\ r\leq-20 \end{gathered}

The correct description of the graph is:

a solid circle at -20 and an arrow pointing left.

Hence, Haley is correct.
