## Math Problem Statement

using the pairs of values for all 10 points in the picture above, find the equation of the regression line rounded to three decimal places. After removing the point with coordinates (1,2) use the pairs of values for the remaining 9 points and find the equation of the regression line. Compare the results from parts an and b after.
