Let T : R? → R? be the linear transformation which reflects across the line y = -2x and then
-3x-4y
%3D
-4x +3y
stretches in the x and y directions, each by a factor of 5. That is, T
3.1
Verify, using what we've learned in class, that the formula given for T indeed performs
the transformation described geometrically above (reflecting across y = -2x and stretching by a
factor of 5.)
3.2
Sketch a single copy of R2 which contains the following:
• T(e1) and T(e2),
• The fundamental parallelogram for T (i.e. the image of the unit square under T),
• The line y = -2x.
3.3
Explain why your drawing from the previous part implies that neither e nor ez is an
eigenvector for AT.
3.4
Determine two basic eigenvectors vị and v2 for AT (you do not need to determine the
eigenvalue(s) associated to those basic eigenvectors).
Justify your answer using only a geometric explanation explicitly relying on and referring to your
drawing from the previous part, or to a new drawing, if you wish.
Note: Algebraic work will not be marked for parts 3.3 and 3.4 of this question. For instance, computations
involving AT will be ignored. Instead you need to justify your answers purely using picture(s) and
explanations relying on those picture(s).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa39a0292-955d-43cc-aa67-690c8fee190d%2F9616983f-603e-451d-9db5-8e27c6bbfc83%2Fmnj3kx_processed.jpeg&w=3840&q=75)
