I need a suggestion/advice/inputs from the mathematicians here.

I have collected data of number of instructions/sec executed by a processor every second, number of loads/stores performed every second and stored the array of values in 2 files.

I also simultaneously collected data of the energy consumed every second by the entire computer and stored it in a file.

Assuming [A] to be an array of number of instructions executed/sec and [B] is the array of loads/stores every second, [C] is the array of energy values every second, how can i find an equation of the form Ax+By = C ?

Should I use curve fitting ? What is the approach I should employ? Eigen vectors ? I'm a bit out of touch with Mathematics since it's been quite long.
