In this question, x represents years. The y represents how much employees are paid. Since the slope is positive, it is rising on both the x- and y-axis. If you were to graph this equation, you would see that, when an additional year passes, $0.65 is added to the employee's hourly wage from the original $5.15 (which is the y-intercept) So the answer is B. An additional year of service is associated with an additional $0.65 per hour.
