سؤال 8

Select all statements that are true about the distance between 2 and -6 on a number line.

The distance is 8 units.پاسخ درست
Measuring from -6 to 2 gives the same distance.پاسخ درست
Measuring from 2 to -6 gives -8 units, because the move runs to the left.
The distance is 4 units, since the two values differ by 4 in magnitude.

توضیح

The walk is counted step by step, six from -6 up to zero and two more from zero onwards, and that count does not care which end it begins at. A signed result records a direction of travel instead, and the separation of two distinct marks can never come out below nothing.
