The true statements are
A 1 pound of blueberries cost $2.75
D 12 pounds of blueberries cost $33
How to find the true statements
The graph is a linear proportional graph.
The constant of proportionality, k is calculated by
k = y/x
From the graph
k = 16.5/6
k = 2.75
For x = 1
y = 2.75 * 1 = 2.75 (option A is correct)
For x = 2.75
y = 2.75 * 2.75 = 7.56 (option B is incorrect)
For x = 5
y = 2.75 * 5 = 13.75 (option C is incorrect)
For x = 12
y = 2.75 * 12 = 33 (option D is correct)
For x = 3
y = 2.75 * 3 = 8.25 (option E is incorrect)
