A botanist gathered data about the number of pine, oak, and birch trees found in local parks. He used a graphing tool to organize his data in different scatter plots and found the following lines of best fit:

The relationship between the numbers of pine trees, x, and oak trees, y, is modeled by the equation y = 0.92x + 2.14, and the correlation coefficient for the data is 0.664.
The relationship between the numbers of birch trees, x, and oak trees, y, is modeled by the equation y = 0.73x + 1.13, and the correlation coefficient for the data is 0.939.
The relationship between the numbers of birch trees, x, and pine trees, y, is modeled by the equation y = 0.88x + 5.12, and the correlation coefficient for the data is 0.813.
Which line of best fit can the botanist expect to produce the most reliable predictions?
