Use the image to answer the question.

A vertical line separates 2 triangles. The triangle to the left of the line is made up of points upper P, upper Q, and upper R, while the triangle on the right is made up of points upper P prime, upper Q prime, and upper R prime.

Triangle PQR
is reflected over a vertical line of reflection to create triangle P′Q′R′
. What are the coordinates of point R′
?

Based on the image, the triangle PQR is reflected over a vertical line of reflection. Since a vertical line of reflection does not change the x-coordinate but negates the y-coordinate, we can determine the coordinates of point R' by negating the y-coordinate of point R.

Therefore, the correct answer is:
