What is distance between ( -9 ) and ( -1 )
Answer and explanation
Correct answer: 8
The distance between two numbers on a number line is their absolute difference: \(\lvert -9-(-1)\rvert=\lvert -8\rvert=8\). Therefore, the correct answer is 8. The number 9 is only the absolute value of \(-9\), not the distance between the two points. Exam tip: a distance is always non-negative.
