Which numbers are a distance of 7 units from -2 on a number line

Hi there!

The answers are -9 and 5.

Step-by-step explanation:

On a number line you can either go left (towards the negative side) or right (towards the positive side) since it is asking what numbers are a distance of 7 units from -2, there are two methods you must use;

-2 + 7 means you are moving 7 units to the right and you get 5

-2 -7  means you are moving 7  units to the left and you get -9

9 and -9

Step-by-step explanation: First, identify the problem. Then, subtract it in both ways. -2 minus 7 and 7 minus -2. Simple. You should be able to acquire your answers quite easily if you subtract properly. After all that, you should end up with 9 and -9. If you did not, however, you subtracted wrong. Thank you for reading!
