Match the equation with its graph. \( y=-2 \)

This equation represents a horizontal line where the y-value is consistently -2, regardless of the x-value. Picture a straight line running parallel to the x-axis, slicing through the y-axis at -2. It doesn’t matter where you look on this line; all points will maintain the same height! To visualize this, imagine standing on a flat plateau at the y-level of -2. If you take a step left or right (along the x-axis), the elevation doesn’t change one bit—you're still at the same height of -2. That's the beauty and simplicity of horizontal lines in graphs!
