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

Mar 24, 2015

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

$x + 2 y = - 2$

(Subtract $x$ from both sides.)

$2 y = - 2 - x$

(Divide both sides by 2.)

$\frac{\cancel{2} y}{\cancel{2}} = \frac{- \cancel{2}}{\cancel{2}} - \frac{x}{2}$

$y = \frac{- x}{2} - 1$

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