Answer 1

The answer is point C , -(-10)

Explanation:

It’s -(-10) because when you multiply negative times a negative they cancel out and turn into a positive. Also, when looking where point A is, if you count how far it is away from 0, it’s ten. Then when you see where C is from 0 it’s also ten steps away. Therefore the opposite point of A is point C.
