The two numbers 2 and 17.
The distance between two numbers is represented by their difference. As the distance is always a positive quantity, the absolute value function is used over the distance to prevent a negative distance.
The distance between points x and y is given by
Put 2 for x and 17 for
The absolute value function is defined by
Since -15 < 0, it can be concluded that
The distance between the points 2 and 17 is expressed as
