Answer by neatmath(302)   (Show Source):
You can put this solution on YOUR website! Well, you don't really need a number line to solve this.
Whenever you use absolute value, you are in a sense, just finding the number's distance from the number line.
Absolute value is defined as this for |x|:
If x<0, then |x|=-x
If x>=0, then |x|=x
So for your first example, you have -3 and +1
The absolute value of -3 is 3
The absolute value of +1 is 1
3 is bigger than 1, so -3 has a bigger absolute value!
For your second example of -2 and +4
The absolute value of -2 is 2
The absolute value of +4 is 4
Thus +4 would have the bigger absolute value.
And in both cases, the number with the BIGGER absolute value would be farther away from zero on the number line.
In general, the farther away you get from zero on the number line, the bigger the absolute value of those numbers!!!
I hope this helps!
