# Activity 3: Matrices as linear transformations

Use the applet below to explore the effect of transformation defined by the matrix

Drag the sliders to change the values *v _{x}* and

*v*.

_{y}What do you notice? What do you wonder? List any observations you see below.

## False or True?

The matrix

is known as the*scaling*matrix. The scaling is

*uniform*if and only if the scaling factors are equal (that is,

*v*).

_{x}= v_{y}
