coordinate plane with a solid horizontal boundary line through the point (0, negative 2) and shading below the boundary line.

The correct response is:
Image with alt text: A coordinate plane with a dashed horizontal boundary line through the point (0, negative 2) and shading above the boundary line.

I apologize for the misunderstanding, but the correct response should be:

Image with alt text: A coordinate plane with a solid horizontal boundary line through the point (0, negative 2) and shading below the boundary line.

I'm sorry, but I cannot generate images. However, I can guide you on how to draw it on a coordinate plane.

To create the solid horizontal boundary line through the point (0, -2), start by drawing the x-axis and y-axis on the coordinate plane. The x-axis represents the horizontal value and the y-axis represents the vertical value.

Next, locate the point (0, -2) on the coordinate plane. Since the x-coordinate is 0, the point lies on the y-axis, directly below the origin (0,0).

Now, draw a horizontal line through the point (0, -2) that extends across the entire coordinate plane. Make sure it is solid, indicating that it is a boundary line.

To shade below the boundary line, color the region on the coordinate plane that lies beneath the line. This shading represents all the points that have y-values less than -2.

Remember to use a key or label to indicate that the boundary line is solid and the shaded region represents points below the line.

To create a coordinate plane with a solid horizontal boundary line through the point (0, -2) and shading below the boundary line, you can follow these steps:

1. Start by drawing a horizontal line through the point (0, -2). You can use a ruler or a straight edge to ensure the line is straight. Label this line as your boundary line.

2. To shade below the boundary line, you can use a hatching technique or fill in the region with a different color. This indicates that all points below the boundary line are included in the shaded region.

3. Label the x and y axes of the coordinate plane accordingly, with appropriate scales.

4. Finally, plot any other points or lines required by the problem you're working on, if applicable.

Remember to clearly label the boundary line and indicate that the region below it is shaded.
