Answer

The graph is attached.

Work Step by Step

First, make sure that the absolute value is in the form $y=a\mid x-h\mid +k$. Next, find the vertex of the function, which will be at $(h,k)$. Finally, knowing that $a$ is the slope, graph the entire function. **Note, the graph of $y=\mid x\mid$ is included for comparison, as the problem requests. It is in red.
