First figure out the dilation factor. The dilation factor is what the original sides are multiplied by to get to the dimensions of the new figure. For example, if the new figure has sides that are twice the lengths of the original, then the dilation factor is 2. I see that the distance from Y to Z is 3 units, while the distance from x' to y' in the new figure is 6 units. So the dilation factor must be 2. The y-axis separates these figures, so the line of reflection must be the y-axis.
