Assume the relationship is linear. The regression line (or trendline), equation, and coefficient of determination (R2) for the data are shown on the graph below. Part A: In 1959, carbon dioxide concentration was about 316 parts per million (ppm). By 2000, it had risen to about 370 ppm. Determine the total growth in carbon dioxide concentration from 1959 to 2000 and express your result as a percentage change, rounded to the nearest whole percentage point. Hint Answer: % Part B: According to the trendline of the graph, what is the rate of annual change/increase in carbon dioxide concentration? Do not round your answer. Hint Answer: ppm per year
