Question

The best way is to show examples

So let's start with a number line

|dw:1372896278965:dw|

jim_thompson5910 · Answer

now let's say we had the inequality 

|dw:1372896384544:dw|

jim_thompson5910 · Answer

there is no line under the inequality sign and the sign is a greater than sign

so we draw an open circle at 2, then shade to the right like this

|dw:1372896426898:dw|
