Respuesta :

Answer:

A. rotation 180º about the origin

Step-by-step explanation:

Taking two points:

Old coordinates:

Q(2,0), F(2,4)

New coordinates:

Q'(-2,0), F(-2,-4)

The rule is:

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

Which describes a rotation of 180º about the origin, and the correct answer is given by option a.
