Answer:
B. and E.)
Step-by-step explanation:
When the question asks about opposites of the points on the number line, it is basically like a mirror reflection of where they are. I'll explain:
B.) This answer is correct, because if you look at points S and Z, you'll see that point S in on -20, and point Z is on 20. This is a perfect reflection of these two numbers on the line, because -20 is the opposite of 20.
E.) This answer is also correct, because point W is also a perfect reflection of point X. Point W is on the number -5, while point X is on the number 5. This shows a perfect reflection of point W (-5) to point X (positive 5).
The other letters (A, C, D, and F) are all incorrect because they do not show perfect reflections of their number's opposite.
I hope that this helps.
