Find Vout/Vin and the input resistance for the following circuit.

		Vin/Vout = -2, Rin = 100
		Vin/Vout = -2, Rin = 200
		Vin/Vout = -2.5, Rin = 100
		Vin/Vout = -2.5, Rin = 200
		Vin/Vout = -3, Rin = 100
		Vin/Vout = 2, Rin = 100
		Vin/Vout = 2, Rin = 200
		Vin/Vout = 2.5, Rin = 100
		Vin/Vout = 2.5, Rin = 200
		None of the above
