A tank had 6 liters of water. The tank had a small hole in its base through which water leaked out at a constant rate. The tank was empty after 4 minutes. If y represents the number of liters of water in the tank and x represents the time in minutes, which graph best represents this situation?

Based on the given problem above, if we analyze it, we are going to look for the graph which with coordinates (0,6) which represents starting out with 6 gallons, and ending at (4,0). So, the graph that best represents this situation would be the first graph on the top left. Hope this answers your question. Have a great day!
