1. The problem statement, all variables and given/known data Let A be the matrix of the linear transformation T. Without writing A, find an eigenvalue of A and describe the eigenspace. T is the transformation on R2 that reflects points across some line through the origin. 3. The attempt at a solution Since they tell us that the point is reflected across the origin, I say that the eigenvalue= -1 and since T is a linear transformation, the eigenspace is in R2. Are both the answer and reasoning correct?
