2 3 4 5 Question Example Step by Step If a transformation moves points only up or down, how do the coordinates of the point change? What can you conclude about the coordinate notation for the transformation? The x-coordinate v does not change. The y-coordinate v has a positive constant added to it (for a translation up) or a negative constant added to it (translation down). The coordinate notation has the form (x, y) - , where b is a real number, b / 0
