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 yaxis.
I'm not sure how to do this. Is there a certain formula I need to know?
The reflection across the yaxis negates the x coordinates. The y coordinates remain the same.
