Final answer:
The question does not provide the specific statements to evaluate, but generally, a graph of trail mix consumed at a constant rate would show a linear decrease. Correct analysis requires the actual data and statements.
Step-by-step explanation:
Without the specific statements provided in the question, it's impossible to determine which statements about the graph showing the amount of trail mix remaining are true. However, in general, when a family purchases a bag of trail mix and eats the same amount each day, the graph representing the amount remaining would typically show a linear decrease over time. This assumes no additional trail mix is added and the amount consumed does not change day to day.
