This is a multiple linear regression problem.

Consider this dataset that consists of 5 data points (2:, 3;) which are listed in the rst two columns below. Y X U X\" U\" 2 2 1 1 1 1 1 l] 1 3 1 1 4 2 1 We are interested in properties of the optimal model point 15=1X+t3U 2. Use the results of 1 to find m and b. 3. Verify that the regression line y = ma + b passes through the mean point (@, y) in the data set. (This is a general property all linear regression lines: they always pass through the mean point in the scatter plot.)
