Answer:

a) the x-coordinate changes sign

b) the y-coordinates are unchanged

c) this is a reflection across the y-axis

Explanation:

a)

Each image point is on the same horizontal line as the original. It is as far from the y-axis as the original, but in the opposite direction. Its x-coordinate has changed sign.

__

b)

The y-coordinate is the same for each image point as for the original. The y-coordinates have not changed.

__

c)

The line of reflection is the perpendicular bisector of the segment joining the original point and its image. In every case, that is the y-axis. The image is a reflection across the y-axis.
