Is the image directly above/below the preimage? Is the image directly to the left/right of the preimage?
Neither
Practice makes perfect
A figure that is reflected in the x-axis would have it's image directly below or above it on the opposite side of that axis. By the same reasoning, a figure reflected in the y-axis, would have an image to the left or right of it on the opposite side of that axis. With this in mind, let's consider the given diagram.
We see above that the triangles are neither directly above nor below each other. Therefore, the transformation shown is not a reflection in the x-axis. We can also see that the triangles are not directly next to each other. Hence, the transformation is not a reflection in the y-axis. The answer is neither.
