Recall that translations in the coordinate plane involve shifting a figure without rotating or resizing it.
Understand that moving a figure to the right means increasing its x-coordinate values while keeping the y-coordinates the same.
Recognize that a horizontal translation affects the x-coordinate, while a vertical translation affects the y-coordinate.
Since the figure moves to the right, this corresponds to a positive change in the x-direction, which is called a horizontal translation in the positive x-direction.
Therefore, the correct description of the transformation is a horizontal translation in the positive x-direction.
