Use the drop-down menus to complete the statements to match the information shown by the graph. A graph has time (minutes) on the x-axis, and water in pool (gallons) on the y-axis. A line labeled pool B goes through (0, 0) and has a positive slope. A line labeled pool A starts at a point above (0, 0) and has positive slope. CLEAR CHECK Pool A is filling up Pool B because the of the graph for Pool A is that of the graph for Pool B. The of the graph tells you the unit rate in .
