Question

On a number line, the distance from zero to -9 is 9 units.

Which equation demonstrates this concept?
A.
0 + 9 = 9
B.
|-9| = -9
C.
|-9| = 9
D.
92 = 81

Answer 1

The answer is C because the absolute value of any negative number is its positive number counterpart. If it we're positive, however it would still be 9 because that is the distance from 9 to zero.

Just to conclude, the answer is C. Sorry for the long answer; I hope this helps!

Answer 2

C. |-9| = 9

Explanation:

Distance is always non-negative. Distances in a negative direction are made positive by the use of the absolute value function. The distance from 0 to -9 is one such distance.
