Rules of Coordinate Grid

What is the result of reflecting a point across the y-axis?

• Both the x-coordinate and the y-coordinate are the same value as the original point.

• Both the x-coordinate and y-coordinate are opposite in value as the original point.

• The x-coordinate is opposite in value while the y-coordinate is the same value as the original point.

• The x-coordinate is the same value and the y-coordinate is opposite in value of the original point.
