How do you represent the inequality r ≥ -6 on a number line?

Back

You draw a closed circle on -6 and shade to the right.

Front

What does an open circle on a number line indicate?

Back

An open circle indicates that the number is not included in the solution.

Front

What does a closed circle on a number line indicate?

Back

A closed circle indicates that the number is included in the solution.

If x ≥ 15, how would you graph this inequality?

Back

You would draw a closed circle on 15 and shade to the right.

Front

What inequality does the number line with a closed circle at 4 and shading to the left represent?

Back

The inequality x ≤ 4.

Front

If a graph shows shading to the left of -4, what inequality does it represent?

Back

The inequality x < -4.
