Your weight is the result of the gravitational force on Earth on your body. What is the corresponding reaction force?

Your weight is the gravitational force of the Earth on your body. By Newton's Third Law, all forces come in pairs. The "reaction force" in this case is the force from your body on the Earth. You pull up on the Earth with the same magnitude of force that the Earth pulls down on you.

Your teacher is confused.
Reaction to gravitational force mg acting on you is the force of your gravity acting on planet earth (pulling planet earth upward).
Reaction to your weight W acting on the floor is force with witch the floor pushes you upwards. This force is usually called normal reaction of the floor N.
Your 'weight W' might be the result of the 'gravitational force mg' acting on you, but they are two different forces acting on two differnt bodies.

the force of the earth acting up on an object is called the normal force
the normal force works perpendicular to the surface, so it decreases if the object is on a slope

equal and opposite
actio = reactio
Newtons 3rd Law
