Use the drawing tool(s) to form the correct answer on the provided graph. 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.
