What is the 1 by 1 row matrix column 1 cap A sub y in the given system of linear equations? negative 8 x plus y is equal to negative 6 3 x minus 2 y is equal to negative 1

To form A_y, replace the y-coefficient column of the system’s coefficient matrix with the constants on the right side. The x-coefficients stay −8 and 3, while the constants are −6 and −1, so A_y = [[−8, −6], [3, −1]]. This is choice D.
