Points on number line

-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.

Were is the diagram?

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
