Question

Which could represent the distance between –12 and 4 on a number line? (Select all that apply


4 - (-12)


4 -12


|4- (-12)|


|-12 -4|


12-4

Answer 1

Correct choices: 4 - (-12), |4 - (-12)|, and |-12 - 4|.

Reason: distance = |4 - (-12)| = |(-12) - 4| = 16. 4 - (-12) = 16 as well. 4 - 12 = -8 and 12 - 4 = 8, which are not the distance.
