Answer
Refer to the image below for the graph.
Work Step by Step
The given interval involves an open parentheses.
This means that the lower limit (which is $-8$) is not included in the set.
The given interval is unbounded on the right.
Therefore, the given interval is equivalent to:
$x \gt -8$
To graph this on a number line, plot a hollow dot (or a hole) at $-8$, then shade the region to its right.
(Refer to the attached image in the answer part above.)
