Ms. Lopez, a fitness coach, studied the relationship between weekly exercise hours and resting heart rates (in beats per minute, bpm) of her clients. She collected data from several clients, where \(x\) represents the hours of exercise per week and \(y\) represents the resting heart rate. After analysis, she derived the best-fit line equation: \(y = -2x + 80\). Using this equation, estimate the resting heart rate for a client who exercises 6 hours per week.
