In the given number line point A is on the left of 0 at number -2 on the number line while point B is on the right of 0 at number 12.
The distance of A to 0 is 2 units .Point B is at a distance of 12 units from 0. The distance between a number's place on the number line and 0 is called the number's [absolute value]
A and B are l-2 l+12= 2+12 =14 units apart from each other.
Distance AB= 12+2=14 units.
