## Matrices as transformations

To graphically explore the application of a matrix, see how it acts on the standard vectors $(1,0)$ and $(0,1)$. Then piece together the effect on the overall shape by considering the $x$ and $y$ behaviors separately.
One way to determine how a shape is transformed by application of a matrix is to directly compute the matrix multiplication on several key points of that shape.
