Question

Which of the following expressions represents the distance between -4 and 1

a) ∣−4+1∣
b) ∣−4−1∣
c) None of the above

Answer 1

b) |-4 - 1| represents the distance between -4 and 1.

There are 5 units between -4 and 1, as shown in the number line.

-4 - 1 = -5, but since there are absolute value bars, the |-4 - 1| = 5.
