**Title: Calculating the Regression Line for Annual High Temperatures****Introduction:**Annual high temperatures in a certain location have been tracked for several years. Let $ X $ represent the year and $ Y $ the high temperature. Based on the data shown below, calculate the regression line (each value to two decimal places).**Data Table:**| $ x $ | $ y $ ||---------|----------|| 2 | 6.53 || 3 | 3.04 || 4 | 6.25 || 5 | 3.06 || 6 | 6.17 || 7 | 3.58 || 8 | 3.49 || 9 | 3.10 |**Task:**Determine the equation of the regression line in the form $ y = mx + b $.**Note:**It involves calculating the slope ($ m $) and y-intercept ($ b $) using statistical methods such as least squares. The values should be rounded to two decimal places.**Conclusion:**This exercise helps in understanding the relationship between the year and the recorded high temperature, allowing for prediction and analysis of trends over time.

Given that Let X represent the year and Y the high temperature.... The data of X and Y is given in the table We have to find the regression line y on x Or Simple linear regression line As follows
