Please see the graph, made using graphing software.

Work Step by Step

$x+y > -2$ To find the boundary line, the $>$ sign is replaced with an $=$ sign. $x+y=-2$ Let $x=0$ (y-intercept) $x+y=-2$ $0+y=-2$ $y=-2$ Let $y=0$ (x-intercept) $x+y=-2$ $x+0=-2$ $x=-2$ $(0, -2)$ and $(-2,0)$ are on the line. Use $(0,0)$ to determine what side of the line to shade. $x+y>-2$ $0+0 > -2$ $0 > -2$ is a true statement, so we shade the side of the line with $(0,0)$.
