Automated tractors can mow lawns without being driven by a person. A company runs trials using fields of different sizes, and records the amount of time it takes the tractor to mow each field. The field sizes are measured in acres. Can the time to mow acres of a field be represented by a linear function? If yes, find the equation of the function.
