Answer 2

The correct answer is:

2

Step-by-step explanation:

There are two directions from 0 on a number line, to the left and to the right.

Numbers to the left of 0 on a number line are negative numbers; numbers to the right of 0 on a number line are positive numbers.

The number 10 units to the left of 0 on a number line is -10, and the number 10 units to the right of 0 on a number line is 10; there are two answers.
