Answer:
IT'S D
Step-by-step explanation:
D. (x-3, y+1): This vector moves the triangle leftward by 3 units and upward by 1 unit. Since the triangle was reflected across the y-axis, the x-coordinates of the points should be negated. In this case, the given translation vector (x-3) negates the x-coordinate, which aligns with the reflection. Therefore, option D is the correct answer.
