#x <= -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.
