Final answer:
The distance between Point A located at -5/8 and Point B located at -2/8 is found to be 3/8 units by subtracting and taking the absolute value. The correct answer is (a) 3/8 units.
Step-by-step explanation:
The distance between points A and B on a number line can be found by subtracting the coordinates of point A from the coordinates of point B and taking the absolute value, as distance is always a positive quantity. In this case, Point A is located at -5/8, and Point B is located at -2/8. Therefore, to find the distance between points A and B, we subtract the coordinate of point A from the coordinate of point B:
-2/8 - (-5/8) = -2/8 + 5/8 = 3/8
Since distance cannot be negative, the distance between points A and B is 3/8 units. Therefore, the correct answer is (a) 3/8 units.
