What is distance between ( -1 ) and ( 8 )
Answer and explanation
Correct answer: \(9\)
On a number line, the distance between two numbers is the absolute value of their difference: \(\lvert 8-(-1)\rvert=\lvert 9\rvert=9\). Hence, the correct answer is \(9\). Choosing \(7\) usually results from an error while subtracting a negative number. Exam tip: a distance is always non-negative.
