Find the distance between points M (-7,1) and N (4,2) on the coordinate line.

First, the distance is a positive value, that is, the result must always be greater than zero.

To find the distance, you need to subtract the smaller one from the larger coordinate.

The point with the larger coordinate is located on the coordinate line to the right, with the smaller one – to the left.

Point N (4,2) is to the right, its coordinate is larger, M (-7.1) is to the left, its coordinate is smaller.

4.2 – (- 7.1) = 4.2 + 7.1 = 11.3. (if there are two minuses in front of the number, they must be replaced with one plus)

Answer: 11.3.
