Q. Tony is using a math app to help him study for a quiz on integers. He knows that if the app shows the integer

8

, he needs to move

8

spots to the right on the number line.

\newline

If the app shows the integer

-7

, what does Tony need to do?

\newline

Choices:

\newline

(A)move

7

spots to the left

\newline

(B)move neither left nor right

\newline

(C)move
