Step-by-step explanation:
| x - 2 | < 4
Start at x=2. Go 4 units in either direction: x=-2 and x=6. Draw empty circles around each. Since it's less than, the line goes between the circles, connecting them. The result should look like this:

| x + 2 | > 4
Start at x=-2. Go 4 units in either direction: x=-6 and x=2. Draw empty circles around each. Since it's greater than, the line goes outside of the circles. The result should look like this:
