How do you graph y= abs(3x+6)?

Jun 4, 2016

Answer:

$y = | 3 x + 6 |$ represents the pair of lines $y = \pm \left(3 x + 6\right)$. The common point is $\left(- 2 , 0\right)$. Another point on the first line is $\left(0 , 6\right) . \left(0 , - 6\right)$ is on the second line.

Explanation:

$y = | 3 x + 6 |$ is the combined equation for the pair of straight lines $y + \pm \left(3 x + 6\right)$.

Solving, the point of intersection is $\left(- 2. 0\right)$.

Another point on the first line is $\left(0 , 6\right) . \left(0 , - 6\right)$ is on the second line.
