**Instructions for Calculating Regression Line**Based on the data shown below, calculate the regression line (each value to two decimal places):\[ \text{y} = (\text{Enter value}) \cdot \text{x} + (\text{Enter value}) \]**Data Table:**| x | y ||---|-----|| 2 | 4.5 || 3 | 4.85|| 4 | 4.4 || 5 | 5.05|| 6 | 6.2 || 7 | 4.45|| 8 | 5.4 |**Explanation:**To determine the regression line, you will use the method of least squares to find the best-fitting straight line through these points. The line is expressed in the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. Make sure to round your results to two decimal places.
