Two points are plotted on a number line: −11.2 and 3.3. 

What is the distance between these two points?

• 7.9

• 14.5

• -7.9

• -14.5

Answer explanation

The distance between points A and B on a number line is the absolute value of the difference between those two points. Distance is always a positive value. Evaluate the difference between the points and then apply the absolute value:

AB = |b − a| or |a − b|

= |−11.2 − 3.3|
= |−14.5|
= 14.5

Recall that the absolute value of a number is its distance from 0.

Which expression correctly represents the distance between

the two points marked on this number line?

Answer explanation

Begin by labeling the point values. The number line shows markers every 1 space with labels every 2 spaces. The point halfway between −5 and −6 must be −5½, and the point midway between 0 and 2 must be 1. To determine the distance between these points, evaluate the difference and take the absolute value:

AB = |b − a| or |a − b|

= |−5½ − 1|
= |−6½|
= 6½
