Barbara plotted an elevation below sea level on a number line and labeled it A. She plotted Point B above 0, a distance that is exactly as far from 0 as Point A is. Explain what you know about Point B.

Point A is the same distance below 0 as Point B is above 0.

Point B is a positive integer.

Since a number and its opposite are the same distance from 0 in opposite directions, Point B is the opposite of Point A.

Explanation:

Sample Response: Because Point A is negative and the same distance below 0 on the number line as Point B is above it, Point B is both positive and the opposite of Point A.
