The system of inequalities represented by the graph is:

y ≥ 3x + 6 (represented by the line passing through the points (0, 6) and (-2, 0) with shaded region above the line)

y < -x - 6 (represented by the line passing through the points (0, -6) and (-6, 0) with shaded region below the line)

y ≥ 3x + 6 (Option D)

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
