## Transformation of Regions in the Plane

In this educational example, we explore a transformation from a region \( S \) in the \( uv \)-plane to a region \( R \) in the \( xy \)-plane. The aim is to find equations for a transformation \( T \) that maps the rectangular region \( S \), aligned with the \( u \)- and \( v \)-axes, onto the region \( R \).

### Description of Regions

- **Region \( R \)**: 
  - Bounded by the lines \( y = 2x - 4 \), \( y = 2x + 4 \), \( y = 4 - x \), and \( y = 6 - x \).
  - Graphically represented in the \( xy \)-plane as a shaded quadrilateral oriented at an angle.

- **Region \( S \)**:
  - Shown as a rectangle in the \( uv \)-plane.
  - The sides of \( S \) are parallel to the \( u \)- and \( v \)-axes, making it easier to visualize its rectangular shape and orientation.

### Visual Explanation

- **Graphs**:
  - The left graph represents the \( uv \)-plane with region \( S \) shaded as a rectangle. The axes are labeled \( u \) and \( v \), with the \( u \)-axis ranging approximately from -6 to 6 and the \( v \)-axis from 1 to 6.
  - The right graph illustrates the \( xy \)-plane, where region \( R \) appears as a rotated rectangle bounded by the provided line equations. The axes are labeled \( x \) and \( y \), both ranging from about 0 to 6.

### Objective

The goal is to determine a set of equations that define the transformation \( T \), mapping \( S \) to \( R \). These equations need to account for the orientation and alignment differences between \( S \) and \( R \).

### Constraints

- The mathematical relationship must ensure that the sides of \( S \) remain parallel to the \( u \) and \( v \) axes during transformation.
- The equations provided will be a comma-separated list, aligning the coordinates from the \( uv \)-plane to the \( xy \)-plane correctly.

By understanding and applying transformations, we can map and manipulate geometrical regions effectively across coordinate systems.
