I need help with vertices!

The vertices of triangle FGH are F(1,1), G(3,-5),H(6,0). Find the coordinates of the vertices after a refelection over the y-axis.

I'm not sure how to do this. Is there a certain formula I need to know?

The reflection across the y-axis negates the x coordinates. The y coordinates remain the same.
