The electric resistance R of a certain resistor is a function of the temperature T given by

Question:

The electric resistance R of a certain resistor is a function of the temperature T given by the equation R = aT + b, where a and b are constants. If R = 1200Ω when T = 10.0°C and R = 1280Ω when T = 50.0°C, we can find the constants a and b by substituting and obtaining the equations

1200 = 10.0a + b

1280 = 50.0a + b

Are the constants a = 4.00Ω /°C and b = 1160Ω?
