Sharon is rowing a boat upstream. the river is flowing at a speed of 3 miles per hour. sharon starts rowing at a speed of 8 miles per hour, but as she gets tired her speed decreases (at a rate of 1.5 miles per hour, every hour). graph the equation that fits the description, where y represents sharon's speed and x represents the time elapsed since the start of her workout.
