Answer:
The ordered pair of W' is (-2,3).
Explanation:
The vertices of trapezoid TUVW are T (4,6) U (7,6) V (7,3) W(2,3).
If a figure reflected over the y-axis, then y-coordinate remains the same but the sign of x-coordinate is changed.

We have to find the image of W after reflection over the y-axis.

Therefore the ordered pair of W' is (-2,3).
