Good OG question

[vish150783]

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


---------A--------B------C------D------E-------------
<--------(-2)----(-1)----(0)----(1)-----(2)-------->

(a) A
(b) B
(c) C
(d) D
(e) E

I want to understand the concept.. could not quite grasp it from OG.

Hi,

Greatest value is defined as the distance from the origin, hence the value of |-2| = |2|. Similarly |-2|>|1|.. hope u can use this concept to answer the question.

But isnt |2| = |-2| = same?

So how do you know if 2 is right or -2 right? because the absolute values of these two values are same.

Are you referring to question 20 on page 154 of OG 11?

[anayeri]

yes, looks like that's the one.

Can someone explain this? Why is -2 any further from the origini than 2?
