Answer:
It's the 4th graph, to the bottom right corner.
Explanation:
Since x is greater than 2, we are looking at everything shaded to the right of 2. The line is also important, if it's a greater than sign or a less than sign, the line will always be dotted. While a greater than or equal to sign, or a less than or equal to sign will always be solid.
Hopes this makes sense :)
