Magnetotransport measurements in several GaAs/GaAIAs heterojunctions show a linear magnetoresistance at 30K <T<120K. At lower temperatures where the quantum Hall effect is observed the magnetoresistance is found to be proportional to the magnetic field times the derivative of the Hall voltage with respect to the field, which can be seen as the extension of the linear magnetoresistance to the quantum regime. A relation between Hall voltage and magnetoresistance valid for all samples and temperatures is given.
