Question

Which distance measures 5 units?

A number line going from negative 8 to positive 8. A closed circle appears at negative 8 and is labeled W. A closed circle appears at negative 3 and is labeled X. A closed circle appears at positive 1 and is labeled Y. A closed circle appears at positive 5 and is labeled Z. An orange arrow line extends the length of the number line and contains all points.

the distance between points W and X
the distance between points X and Y
the distance between points X and Z
the distance between points Y and Z

Answer 1

Distance = absolute difference of coordinates.

W = -8, X = -3, Y = 1, Z = 5.

- W to X: |-8 - (-3)| = | -5 | = 5 → 5 units
- X to Y: |-3 - 1| = 4
- X to Z: |-3 - 5| = 8
- Y to Z: |1 - 5| = 4

So only the distance W–X measures 5 units.
