Solve $x + y < - 1$ $x + y < -1$

rearrange your starting inequality to isolate $y$ $y$ on one side

$y < - x - 1$ $y < - x - 1$

First, graph the line : $y = - x - 1$ $y = - x - 1$ by its 2 intercepts.
Make

$x = 0 \to y = - 1$ $x = 0 -> y = -1$ . make $y = 0 \to x = - 1$ $y = 0 -> x = -1$

The solution set of the inequality is the area below this line. Color or shade it. That is the answer.

graph{y < -x-1 [-10, 10, -5, 5]}
