<image>A washing machine goes through four consecutive processes when washing clothes: water intake, cleaning, water draining, and spin-drying. During the water intake, cleaning, and water draining phases, the relationship between the water amount \( y \) (in liters) and time \( x \) (in minutes) is shown in the line chart. Based on the graph, answer the following questions:  (1) What is the duration of the water intake in minutes? How many liters of water are there in the washing machine during the cleaning phase? (2) It is known that the water draining speed of the washing machine is 19 liters per minute.
   i. Write the equation representing the relationship between the remaining water amount \( y \) (in liters) and time \( x \) (in minutes) during the water draining phase.
   ii. If the water has been draining for 2 minutes, find the remaining water amount in the washing machine at that time.
