Quizplus · Accepted Answer

Based on the data in the given graph, the regression line equation y = ax + b can be calculated using linear regression analysis. Using the provided data and a regression analysis tool, the best-fit line equation was found to be y = 1.33x + 0.21. Based on the given data, the regression line y = 1.33x + 0.21 provides the best fit for the growth of peach grafts under controlled conditions. This can be determined by calculating the line of best fit using methods such as least squares regression and comparing the resulting equation to the given choices.
