Front

What does the inequality x < 4 represent on a number line?

Back

All numbers to the left of 4, not including 4.

Front

What does the inequality x > 2 represent on a number line?

Back

All numbers to the right of 2, not including 2.

Front

What does the inequality x ≥ 2 represent on a number line?

Back

All numbers to the right of 2, including 2.

Front

What does the inequality x ≤ 3 represent on a number line?

Back

Front

How do you represent the inequality x < 2 on a graph?

Back

Draw a number line with an open circle at 2 and shade to the left.

Front

How do you represent the inequality x > 1 on a graph?

Back

Draw a number line with an open circle at 1 and shade to the right.

Front

What is the difference between x < 3 and x ≤ 3?

Back

x < 3 does not include 3, while x ≤ 3 includes 3.

Front

What does an open circle on a graph indicate?

Back

The value at that point is not included in the inequality.

Front

What does a closed circle on a graph indicate?

Back

The value at that point is included in the inequality.

Front

If a graph shows x ≥ 2, what can you say about the number 2?

Back

The number 2 is included in the solution set.
