A reflection is a kind of transformation. It is basically a 'flip' of a shape over the line of reflection.
Triangle ABC coordinates areA(-7,4) and B(7,1). Reflect over the Y AXIS and tell me the reflecting coordinates.
Formula: (-x,y)
New coordinates: (7,4) (-7,1)
(x,-y)

What is the x-axis?
The horizontal axis of a system of coordinates.
Triangle ABC coordinates areA(-6,4) and B(6,1). Reflect over the X AXIS and tell me the reflecting coordinates.
Formula: (x,-y)
Reflected coordinates: (6,-4), (6,-1)
Formula for Reflection of Y axis
(-x,y)
