Question

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. Which distance did Brook measure?
Which distance did Vivian measure?

Answer 1

I don't quite understand the question but from what it's given us so far, I can only assume that it is asking which axis the both of them measured?

Vivian measured the X-Axis, as it said she measured it as 6 units long.

Brook only stated that the distance on the line is 4 units, so I can only assume that she measured the Y-Axis.

I  don't know if this helped but if so please give brainliest :D
