Answer:
The first move, where a shape is moved over the y-axis, is called a "reflection" or "flip" across the y-axis. This means that the shape is flipped or mirrored across the y-axis, causing it to change direction but remain on the same side of the y-axis.
The second move, where the shape is moved 4 units to the right and 2 units up, is called a "translation" or "slide." This means that the shape is shifted horizontally to the right and vertically upward, without changing its orientation.
