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.

mathstudent55 · Answer

If you have a simple "greater than" sign or "less than" sign, you use an open circle.
If you have "greater than or equal to" sign or "less than or equal to" sign, you use a closed circle.

mathstudent55 · Answer

In a simple inequality:
If the answer is greater than or greater than or equal to, shade to the right.
If the answer is less than or less than or equal to, shade to the left.

Let's say you have an equation (not an inequality) whose solution is x = 2. How would you represent that on a number line?

realitywillslapyou · Answer

x = 2
2 = 2
?

mathstudent55 · Answer

You'd simply draw a number line and place a _closed_ circle on 2:
