Ответ:
D
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Thus
(- 5, 6 ) → (- 5, - 6 ) → D
Ответ:
D> (-5, 6) → (-5, -6)
Step-by-step explanation:
Two points are reflections of each other across the x-axis if their
x-coordinates are equal
and
y-coordinates are opposite
