Describe the change that occurs to the coordinates of a vertex of a figure when it is reflected across the y-axis.
a.
the sign of the x-coordinate changes; the y-coordinate stays the same.
b.
the x-coordinate stays the same; the sign of the y-coordinate changes.
c.
both coordinates stay the same.
d.
the sign of each coordinate changes.

To describe the change that occurs to the coordinates of a vertex of a figure when it is reflected across the y-axis, the sign of the x-coordinate changes; the y-coordinate stays the same. The correct answer between all the choices given is the first choice or letter A. I am hoping that this answer has satisfied your query about and it will be able to help you.
