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.)
