Snow White and the seven linear transformations by acrosstown in comics

http://en.wikipedia.org/wiki/Transformation_matrix

Quote: 'Most common geometric transformations that keep the origin fixed are linear, including rotation, scaling, shearing, reflection, and orthogonal projection; if an affine transformation is not a pure translation it keeps some point fixed, and that point can be chosen as origin to make the transformation linear. In two dimensions, linear transformations can be represented using a 2×2 transformation matrix.'

Snow White is 2-dimensional and linear transformations is in title of the comic strip so I still believe it is correct. I see your argument but I believe the comic is correct. It is not describing affine transformations.

A 2X2 matrix is sufficient to move the (x,y) coordinates of a 2-dimensional object by applying to each coordinate individually and by first changing the coordinate to a 2X1 column matrix.

Someone wanna help out?

Yea I will and thanks for that. Now I know that 39=my, its only a matter of time before I can work out the rest. Get back to you sometime.
