Sonji plots –9 on a number line to represent the depth of her sailboat underwater and labels it B. She plots positive 20 on the same number line to represent the height of her sailboat above water and labels it A. Sonji asks if B, the elevation below sea level, acts as an opposite to A, the elevation above sea level. What is the best answer to her question?
