Please look in your text book for this problem Statement  The distance formula between two points on a number line can be used to find the distance between points.

The distance AB = (1)

Or

The distance AB = (2)

From figure; the coordinates of A and B are 2 and 10 respectively. First try the formula (1):

Substitute the coordinate values in the distance formula.

The distance AB =  (Subtract ) The distance is a positive unit and can not be negative, so the absolute value considered.  The distance AB = 8 units. Next, try the formula (2):

Substitute the coordinate values in the distance formula.

The distance AB =  (Subtract ) (Absolute value of 8 is 8)

The distance AB = 8 units. The measure AB is 8 units. TESTIMONIALS
