What is distance between ( -12 ) and ( -3 )
Answer and explanation
Correct answer: \(9\)
The distance between two numbers on a number line is the positive value of their difference: \(\lvert -12-(-3)\rvert=\lvert -9\rvert=9\). Therefore, the correct answer is \(9\). \(15\) is obtained by adding the magnitudes of the numbers, but that is not the distance when both numbers are negative. Exam tip: always use \(\lvert a-b\rvert\) to find distance on a number line.
