### Graph the reflection of the polygon in the given line

#### 1. x-axis
This graph demonstrates the reflection of a polygon across the x-axis. The polygon's original and reflected images are shown on a standard Cartesian coordinate grid.

#### 2. y-axis
This graph demonstrates the reflection of a polygon across the y-axis. The original and reflected images of the polygon are plotted on a Cartesian grid.

#### 3. x = -1
In this graph, the polygon is reflected across the vertical line \(x = -1\). The coordinate system clearly shows the transformation involved.

#### 4. y = 1
This graph shows the polygon's reflection across the horizontal line \(y = 1\). The original and reflected polygons are illustrated on the coordinate grid.

#### 5. y = -x
This graph reflects the polygon across the line \(y = -x\). The coordinate transformation is shown with the initial and reflected images on the grid.

#### 6. y = x
In this example, the polygon is reflected across the line \(y = x\), with the transformation displayed on a standard Cartesian plane.

### Multiple Reflections
The vertices of \( \Delta ABC \) are \( A(-2, 1) \), \( B(3, 4) \), and \( C(3, 1) \). 

1. **Reflect \( \Delta ABC \) in the line \( y = 1 \).**
2. **Reflect \( \Delta A'B'C' \) in the line \( y = -2 \).**
3. **Graph \( \Delta A''B''C'' \).**
  
Each of these reflections is shown on separate graphs:

#### 7. Reflection in \( y = 1 \), then in \( y = -2 \)
This graph demonstrates the cumulative reflection process, first in the line \( y = 1 \) followed by \( y = -2 \).

#### 8. Reflection in \( x = 4 \), then in \( y = -1 \)
Here, the polygon is first reflected in the line \( x = 4 \) and then in \( y = -1 \). The combined transformations are depicted on the grid.

#### 9. Reflection in \( y = x \), then in \( x = -2 \)
This graph reflects the polygon first in the line \( y = x \) and then in
