Answer:
(-1,-3)
Explanation:
See the attached worksheet. First step is to apply the transformation. Modifiy the x and y points as per the instructions. The transformed triangle is shown in blue and the coordinates are listed. As the directions indicate, it is slipped down by 2 and to the left by 3 (y-2 and x-3).
Next, convert the x values so that they are reflected across the y axis. The table shows that all x values are the negative of their original values. The reflected triangle is shown in red.
The new point Z is (-1,-3).
