Question

Points on number line

Answer 1

Answer:

-22 or -2

Step-by-step explanation:

Understanding size

If RS is 10, it does not matter where they are. As long as they are 10 units apart, it works.

However, we already know S lies at -12 so we only have 2 choices for R.

Check the picture I uploaded for better understanding.

This is because RS doesn't mean that R has to be before S. It just means that they are a segment. This means that RS and SR are the same segments.
