Question

Rex mixed x liters of fruit syrup with y liters of water to make a fruit punch. Three times the number of liters of water he mixed was 6 more than twice the number of liters of syrup he mixed. The total number of liters of syrup and water he mixed was 7 liters. Which graph best shows the number of liters of fruit syrup and water that Rex added to make the fruit punch?

Answer 1

The answer is graph 3

Answer 2

 In this case, the graph should be shown as linear since the order is only 1. solving the two equations, the answer is x is 4.5 liters fruit syrup and y is 2.5 liters water.
