coordinates of a quadrilateral are (5, 8), (7, 10), (9, 12), and (11, 14). After a transformation, the sign of the x-coordinate and the sign of the y-coordinate for each ordered pair have changed. Which type of transformation occurred?

A)180° rotation
B)(x,y)→(x + 2, y + 2)
C)reflection across the y-axis
D)reflection across the x-axis

Respuesta :

Answer:

A

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y )

That is the sign of the x- coordinate and the y- coordinate have changed.

Answer:

A)180° rotation

Step-by-step explanation:

A 180°rotation results in the signs of both coordinates changing.
