12. Which of the four labeled points on the number line above has coordinate-?

Answer: B

Explanation:

Point B on the number line has the coordinate -.

Point B is positioned at the coordinate - on the number line, indicating its precise location based on the defined label.

A) A

Point A does not correspond to the coordinate - as it is located at a different position on the number line. The coordinates of point A are not aligned with the specified value, making it an incorrect choice.

B) B

Point B is the correct choice as it accurately represents the coordinate - on the number line. This point is directly aligned with the value being asked about, confirming its correctness.

C) C

Point C is not the correct option because it is situated at a different coordinate that does not match the value of -. Therefore, it fails to satisfy the requirements of the question.

D) D

Point D also does not represent the coordinate -, as its location on the number line is distinct from the specified value. This makes it an incorrect choice in relation to the given question.

Conclusion

Point B is definitively the correct answer as it directly corresponds to the coordinate - on the number line. All other options, A, C, and D, fail to match the required coordinate, which underscores the accuracy of point B's designation.
