$(-1, +\infty)$ Refer to the image below for the graph.
Work Step by Step
The inequality means "x is greater than $-1$." This inequality includes all numbers that are greater than $-1$ (but not including $-1$). Thus, the equivalent interval notation of the given inequality is: $(-1, +\infty)$ To graph this interval, plot a hole (hollow dot) at $-1$ then shade the region to its right. (refer to the attached image in the answer part above)
