Answer
Refer to the image below for the graph.
Work Step by Step
The solutions of $x \gt -3$ are all real numbers that are greater than $-3$.
These numbers are graphed on a number line by shading all points to the right of $-3$.
To graph this inequality, plot a hollow dot (or a hole) at $x=-3$. (Alternatively, an parentheses may be used instead of a hollow dot.)
Then, shade the numbers to the right of $x=-3$.
