An open circle is used for a less than or greater than symbol. A closed circle is used for a less than or equal to, or greater than or equal to symbol.
Both of the functions have negative slopes, which we know because they point to the up and to the left.
The open circle inequality has a y-intercept at (0,2) and the closed circle inequality that is not shown by the image. However, for the closed circle inequality, we know that is must be less than or equal to, because the line goes downwards, away from the closed circle. For the open circle inequality, it must be greater than because the line goes upwards.
This leaves us with answer choices A and B. Looking at both, we can see that the only choice that fits with our observations of greater/less than or equal to, and open/closed is A.
Hope this helps!! :)
