can someone help me with this question on OG11 PS#20.

Of the five coordinates associated with points A,B,C,D and E on the number line above, which has the greatest absolute value?

(A) A
(B) B
(C)C
(D)D
(E)E

The OG guide says the answer in A but then why isnt it E because that is also 2 away from 0

Thanks

OG says:
The distance between the number and zero is called absolute value.
Absolute value of a non zero number is always positive

hence clearly distance b/w 0 and -2 = 2 units is the greater than ditance b/w 0 and other points on the number line.

If the original figure was correct and E was equal to 2 then AC = CE = 2. Thus, what you mentioned would be incorrect
