Question

When reflecting a figure across the y-axis, which coordinate(s) remain the same?

a. polar coordinate
b. x-coordinate
c. y-coordinates
d. inverse coordinates

Answer 1

When reflecting a figure across the y-axis, the x-coordinates of the points are negated, while the y-coordinates remain the same. Therefore, the correct answer is:

**c. y-coordinates**

The y-coordinates stay the same during this reflection.
