The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to mak
Misha Larkins [42]
The ratio of the number of cups of apple juice to lemon-lime soda is 6:1.

If there is a point on the graph at (1, 6), where the x-coordinate the number of cups of lemon-lime soda and y-coordinate is the number of cups of apple juice, you can deduce the ratio (6 cups of apple juice for 1 cup of lemon-lime soda). 

As you imagine on the graph, this pattern continues, with 2 cups of lemon-lime soda for 12 cups of apple juice, that simplifies to 1 cup of lemon-lime soda for 6 cups of apple juice. Since the question asks for the ratio of apple juice to lemon-lime soda, you just reverse the values and get 6:1
