Given:


8x+8\ge-64\text{ and }-7-8x\ge-79

To find the interval:

Solving we get,


\begin{gathered} 8x+8\ge-64 \\ 8x\ge-64-8 \\ 8x\ge-72 \\ x\ge-9\ldots\ldots\ldots..(1) \end{gathered}
\begin{gathered} -7-8x\ge-79 \\ -8x\ge-79+7 \\ -8x\ge-72 \\ x\leq9\ldots\ldots\ldots\ldots(2) \end{gathered}

Therefore, the number line is,
