Need help with this counterclockwise rotation

Mathematics
1 answer:
Mrac [35]3 years ago
7 0

Answer: (-2,1)

Step-by-step explanation:

It is important to remember that a rotation is a transformation in which the shapes and sizes do not change, but the object can be turned in different directions.

By definition, the rule for 180° counterclockwise rotation is this:

(x,y)→ (-x,-y)

Therefore, we know that the image of the point P=(2,-1) under a 180° counterclockwise rotation is:

 (2,-1)→ (-2,1)
