Step-by-step explanation:
The correct answer is: b) Eigenvalue method, differential equations, direction field. The problem is focused on finding a general solution using the eigenvalue method, which is a technique often employed in solving systems of linear differential equations. This method involves determining the eigenvalues and eigenvectors of the coefficient matrix, leading to the diagonalization of the system. This diagonalized form simplifies the solution process. Additionally, constructing a direction field and solution curves through numerical methods or graphing calculators is a common visualization tool for understanding the behavior of the system over time. This combination of techniques is characteristic of solving differential equations and analyzing systems' dynamics.
