The problem asks to reflect the shape over the line $y = -3$. To achieve this, we will follow these steps:

Reflection Process

1. Identify the coordinates of the vertices of the shape: Start by determining the coordinates of the shape's vertices on the grid.

2. Reflect each vertex over the line $y = -3$: For a reflection over a horizontal line like $y = -3$, the distance of each point from the line is the same before and after the reflection. To calculate the reflected point: $y_{\text{new}} = 2y_{\text{line}} - y_{\text{original}}$ where $y_{\text{line}} = -3$.

3. Plot the new points: After calculating the reflected coordinates, plot them and connect to form the new reflected shape.

Would you like me to walk through this process in detail, including calculating the exact coordinates for each point and plotting the reflection? Let me know if you'd like more details or explanations.

Here are 5 related questions to expand on this:

1. How do we reflect a point across the x-axis or y-axis?
2. What is the difference between reflecting over a horizontal line and a vertical line?
3. How can we find the equation of a line that reflects points symmetrically?
4. How does reflection affect the orientation of a shape?
5. What other transformations (like translation or rotation) can be applied after a reflection?

Tip: When reflecting over a line, always check the vertical distance between the point and the reflection line to ensure accuracy.
