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. A number line goes from negative 8 to positive 8. A line with arrows as endpoints is above the line and contains points L, M, N. A closed circle appears at negative 6 and is labeled L. A closed circle appears at negative 2 and is labeled M. A closed circle appears at positive 4 and is labeled N. Which distance did Brook measure? Which distance did Vivian measure?

Hi. You forgot to show the image of the line this question refers to. This makes it difficult for your question to be answered. However, when searching for your question on the internet, I was able to find another question exactly like yours, which showed an image of the line. This line is in the image attached below. If that was your case, I hope this answer can help you:

Brook was measuring the distance between L and M, while Vivian was measuring the distance between M and N.

Explanation:

You will be able to answer this question very simply, as you only need to count the units between every two points on the line. If you count the first unit after point L to the unit that marks point M, you will see that there are 4 units, as Brok noted. If you do the same thing between points M and N, you will see that there are 6 units of distance, as Vivian noted.

sorry idk this one sorry i cant u
