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.

According to Barbara's plot, the number line A, is above sea level, therefore, it's a positive line, in positive range.

On the other hand, the number line B has the same distance but in the opposite direction, is downwards the zero point. So, this means the B line is below sea level, because is in positive range. That's what we can deduct from this, because the characterization Barbara is doing is related to sea level.
