What is distance between ( -9 ) and ( 6 )
Answer and explanation
Correct answer: 15
The distance between two numbers on a number line is the absolute value of their difference. Thus, \(|6-(-9)|=|15|=15\). Therefore, 15 is correct. A result such as 14 may come from handling the negative sign incorrectly. Exam tip: always take the absolute value of the difference, because distance cannot be negative.
