$(-2, 1]$ Refer to the image below for the graph.
Work Step by Step
The inequality has $\lt$ on the left so a parenthesis will be used. The inequality has $\le$ on the right so a bracket will be used. Thus, the equivalent interval notation of the given inequality is: $(-2, 1]$ To graph this interval, plot a hole (hollow dot) at $-2$ and plot a solid dot at $1$. Then, shade the region in between. (refer to the attached image in the answer part above)
