# How do you graph absolute value equations on a coordinate plane?

Let's start with a simple one $y = | x + 2 |$
If $x > - 2$, $x + 2$ is positive, so $y = | x + 2 | = x + 2$
If $x < - 2$, $x + 2$ is negative, but will be 'turned around' by the abslote signs, so in this domain $y = | x + 2 | = - x - 2$
These two semi-graphs meet at $\left(- 2 , 0\right)$
