Find the distance between each pair of points if they were graphed on a number line. Represent your work using absolute value symbols.
Think of the absolute value of an integer as its distance away from
on the number line, so it is always positive.
Because the distance away from
is , and because the absolute value of is , you can add the absolute values to get the distance between them. and
Use the same method as part (a).
This time, the numbers are on the same side of
. How will this change how you find the distance?
