Question

A point undergoes two transformations. The x-coordinate's sign changes and the y-coordinate increases. What were the transformations?
The point was reflected over the y-axis and translated down.
The point was reflected over the x-axis and translated to the right.
The point was reflected over the y-axis and translated up.
The point was reflected over the x-axis and translated to the left.

Answer 1

For this case we are going to define the original coordinates:
 (x, y): original coordinates.
 We apply the transformation:
 (x, y) -------> (-x, y + k)
 We have:
 -x: reflection on the y axis.
 y + k: translation k units up.
 Answer:
 The point was reflected over the y-axis and translated up.

Answer 2

Answer:  The point was reflected over the y-axis and translated up.
