After reflecting the points of triangle GHI over the y axis, the new points will be:
G' (3,0)
H' (5,-5)
I' (-1,-5)
G' (3,0)
H' (5,-5)
I' (-1,-5)

The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same.
If we have some point (x,y) as the original point, then it would turn into (x,-y). Note how the y coordinate has a negative on it now.
So we can say
which is what choice C is saying.
Choice C is the answer
Choice D is NOT the answer because the words "y axis" under the 'r' should be "x axis" instead.
