What does a negative and positive number line look like?
On a vertical number line, positive numbers are located above zero. As we look upward on a vertical number line, the values of the numbers increase. On a vertical number line, negative numbers are located below zero. As we look further down on a vertical number line, the values of the numbers decrease.
How do you show negative numbers on a number line?
