Front

Would you use a closed or open circle to graph x < 3?

Back

Open

Front

What inequality does the number line graph represent? (Assume the graph shows a line starting from -5 and going to the right)

Back

x ≥ -5

Front

What does an open circle on a number line indicate?

Back

The value is not included in the solution set.

Front

What does a closed circle on a number line indicate?

Back

The value is included in the solution set.

Front

How would you graph x ≤ 4 on a number line?

Back

Use a closed circle at 4 and shade to the left.

Front

How would you graph x > -2 on a number line?

Back

Use an open circle at -2 and shade to the right.

Front

What is the solution set for the inequality x < 0?

Back

All numbers less than 0.
