Get the equation of the regression line (rounding parameters to two decimal places), and explain in practical terms the meaning of the slope. In particular, comment on the meaning of the sign of the slope.
Plot the data points and the regression line.
In 2009, 3.62 million domestic cars were sold in the United States. How does the forecast obtained from the regression line compare with this figure?

- Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution. Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forwardPRIMERA EVALUACIÓN SUMATIVA 10.
