$x \le - 1$
graph{x<= -1 [-10, 10, -5, 5]}

Explanation:

First, find the line $x = - 1$.

Since $x$ can be equal to $- 1$ as well, $- 1$ is a point on the graph. so you would draw a sold line.
(if it was $x < - 1$, then the line would be dotted.)

Since you are trying to locate all points whose x-values are less than or equal to -1, shade the portion of the graph to the left of the line. These are all the points whose x-values are less than or equal to -1.
