What is the mapping rule for a 180° rotation?
25
O (x, y) → (), x)
O (2; y) (-, )
* (x, y) – (4, -1)
O (1 )=(-1, -)

(x,y) ---> (-x, -y)

Step-by-step explanation:

(x,y) ---> (-x, -y) is the mapping rule for a 180 degree rotation about the origin.

I also uploaded some picture from the internet for extra info or examples.

(pictures are from calcworkshop.com and slideplayer.com)

I couldn't process the answer choices that are posted in the question.

ok then what happened.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
