Question

Explain, in complete sentences, when you would use an open circle or a closed circle, and when you would shade to the right or left, to graph an inequality on the number line.

My answer is:

You use an open circle when when the point does not equal that value, like if you were doing x>0 or x<0. And you would use a closed circle when it has a equal sign like ≤ or ≥ . You shade to the right if its greater than, and left if its less than.

Am I right?
