A series of voltages, V, have been set and the resulting currents, I, through an electrical device have been read and recorded as follows.

V (volts)         I (amps)

0.34                5.6

0.46                7.2

0.82               10.2

1.20               13.0

1.65               16.5 

2.30               21.0

a) Perform linear regression and write the equation of your best-fit line.

b) What current would you expect from a voltage of 2.0 volts?

c) Can the relationship between voltage and current be described as linear? Explain.
