What does it mean to be symmetric across the y-axis? What do you have to change in the ordered pair?

A. You keep the y-coordinate the same, but change the sign on the x-coordinate in the ordered pair.

B. The point is reflected across the x-axis, like a mirror.

C. The point is reflected across the y-axis, like a mirror.

D. The sign of the y-coordinate changes, but you keep the x-coordinate the same.

Select all that apply.
