We are given $x \lt -1$ Graph the boundary line $x \lt -1$. Since the inequality symbol is $\lt$, the points on the boundary line are not solutions. Use a dashed line to indicate that the points are not included in the solution. To determine which side of the boundary line to shade, test a point that is not on the line. For example, test the point $(0, 0)$. $0 \lt -1$ Because the point $(0, 0)$ is a solution of the inequality, all the points on the same side of the boundary line as $(0, 0)$ are solutions. Shade the area to the left of the boundary line.
