Question

Which expressions represent the distance between the two points?

Choose all answers that are correct.



The number line shows two points with coordinates negative 11 and positive 7.



A.


|–11 – 7|


B.


|–11 + 7|


C.


|7 – (–11)|


D.


–11 – 7

Answer 1

On the number line, the distance between negative 11 and positive 7 is 18 units.

Choice A: The absolute value of (-11 - 7) = absolute value of (-18) = 18.

Choice C: The absolute value of [ 7 - (-11) ] = absolute value of (7+11) = 18.

'A' and 'C' are both the same number, and it's the correct answer to the question.
