** Part 2 8th Final Semester Exam

Raymond drew a triangle with coordinates (4, 6), (2, 1), and (− 2, 3). He drew an image of this triangle with coordinates (2, 6), (0, 1), and (− 4, 3). How did he make this image?

• . He reflected the original figure across the y-axis.

• He translated the figure 2 units down.

• He rotated the figure 90° clockwise about the origin.

• He translated the figure 2 units to the left.
