Which expressions represent the distance between the two points? Choose all answers that are correct. The number line shows two points with coordinates negative 9 and positive 13. A. |–9 – 13| B. |13 – (–9)| C. |–13 + 9| D. 13 – (–9)
In a number line, the distance between the points is the absolute value of their difference. For this given, the distance between points in negative 9 and 13 is the absolute value of -9 minus 13. Thus, the answer is letter A.
