3) Write a general solution in the form Y(o)-kke to a linear system Y'-AY such that solutions living on the line y=9x head directly away fromthe origin, and solutions living on the line y =-2x head directly toward the origin. Of course, the solution at the origin does not move. Hint: You will have some freedom in picking your eigenvalues and eigenvectors, but not total freedom. yi
