Given that Point B is plotted to the right of zero and is exactly as far from zero as Point A is, this means that Point A must be to the left of zero (since it represents yards lost, which are negative values).
Let's analyze the statements:
1. **The sum of the values of Point A and Point B is negative.**
This would be true if Point A is negative and Point B is positive. However, since Point B is exactly the same distance from zero as Point A, they’ll actually cancel each other out in terms of their distance from zero, resulting in a sum of zero. So this statement is not necessarily true.
2. **The sum of the values of Point A and Point B is zero.**
Given that Point A is negative and Point B is positive and they are equal in distance from zero, this statement is correct.
3. **Point B lies twice the distance from 0 as Point A.**
This statement is incorrect because Point B is the same distance from zero as Point A.
4. **Point B lies to the left of Point A on a number line.**
This is false because Point B is to the right of zero, while Point A is to the left of zero; therefore, Point B is actually to the right of Point A.
The correct statement about Point B is:
