Convert the equation to slope-intercept form by solving for $y$ $y$ .

$x + 2 y = - 2$ $x+2y=-2$

(Subtract $x$ $x$ from both sides.)

$2 y = - 2 - x$ $2y=-2-x$

(Divide both sides by 2.)

$(cancel (2)y)/(cancel (2))=(-cancel (2))/(cancel (2))-(x)/(2)$

$y=(-x)/(2)-1$

Values for $x$ and $y$ :
$x=-2, y=0$
$x=0, y=-1$
$x=2, y=-2$

graph{y=-x/2-1 [-8.03, 6.03, -3.945, 3.085]}

How do you graph x + 2y = -2x+2y=−2x + 2y = -2?
