Answer 2

3. 119 and –119

Explanation:

Absolute Value

The absolute value of a number x is the magnitude of x, that is, the positive value of x. This means that if we know the absolute value of a number, that number could be positive or negative.

We know Matthew plotted an integer on a number line whose absolute value is 119. Gabrielle did the same with a different number. We know the absolute value is 119, so the only possible values of their numbers are +119 and -119

Answer: 3. 119 and –119
