Question

Which expressions represent the distance between the two points?

Answer 1

17 points between -15 and 2. Therefore, the correct equations are--

B. |–15 – 2|
&
C. |2 – (–15)|

Answer 2

I am french, and I speak little english (I want to speak well), so please don't read my english errors...

Lesson :

The distance between two points is an absolute value, like : $|a-b|$ (the distance between the point $a$, and the point $b$).

For exemple, the distance between $(-2)$ and $19$ is $|-2+19| = |19-2| = 17$.

Your question :

A. It's not a distance between two points because It's a negative result.
B. It's an absolute value, so it's positive.
C. It's an absolute value, so it's positive.
D. In mathematics, it doesn't mean anything.

So the distance between two points is B, and C.

Have a nice day !
