Options for select box number one: originy-axisx-axisOptions for select box number two:y-coordinatesx-coordinates x and y coordinates

Answer 1

From the image, we can see that the coordinates of the y-values for each of the points changed, but the x-values remained the same.

So, triangle ABC has been reflected over the x-axis to create triangle A'B'C' because the y-values have been changed to their oposite values.
