To determine the number of calories in 1 ounce of soda from the graph, you need to look for the point where the x-axis (ounces) equals 1 and find the corresponding y-value (calories) at that point.
If you are able to provide specific numbers or a description of the graph, I can help you calculate or interpret the value. In a typical proportional relationship, if you can find the ratio of calories to ounces from any point on the graph, you can easily find the number of calories in 1 ounce by scaling down the values.
For instance, if the graph indicates that 12 ounces of soda contains 150 calories, then the number of calories in 1 ounce can be calculated by dividing 150 by 12:
\[ \text{Calories per ounce} = \frac{150 \text{ calories}}{12 \text{ ounces}} = 12.5 \text{ calories per ounce} \]
Please provide the relevant data from the graph so I can assist you more accurately!
