Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long.

Number line are used to represent numbers on a line at regular intervals.

From the number line, we have:

To get the distance between each point, we simply calculate the absolute difference between the points.

Remove absolute bracket

This means that the distance measured by Brook is between L and M

Similarly:

Remove absolute bracket

This means that the distance measured by Vivian is between M and N

In conclusion:
