Think about what a reflection over the y-axis would do to a point: the y coordinate won't change, and the x-coordinate will be the negative of what it was. So each point (a, b) goes to the point (-a, b)

E.g., if I reflect the point (-3, 5) over the y axis, I get the point (3, 5).

Now apply that to your trapezoid.

@ganeshie8 am I missing something in this problem? Why are the coordinates of U needed?

It's only asking about W, so I think that's the only ordered pair that is needed....?
