Which of the following sets of points are reflections of each other across the y-axis?
A. (-6, -9) → (6, -9)
B. (-6, -9) → (6, 9)
C. (-6, -9) → (-6, 9)
D. (-6, -9) → (-9, -6)
The best way to get your answer is to actually graph the points and look to see which is a reflection. Lets Graph. When you graph it, it is shown that A. (-6,-9) -> (6,9) is a reflection.
