The developer of a new plant fertilizer gathered data about the quantity of fertilizer applied to a lemon tree and the number of lemons it produced. He used a graphing tool to organize the data in a scatter plot and find the line of best fit.

He found that the relationship between grams of fertilizer, x, and the number of lemons, y, is modeled by the equation y = 0.316x + 12.214, and the correlation coefficient for the data is 0.948.

Could this line of best fit be used to make reliable predictions?
