Find the equation of a horizontal line going through (-5, -19)

To find the equation of a horizontal line, we need to determine its y-coordinate because a horizontal line has the same y-coordinate for all points on the line.

In this case, we are given that the line passes through the point (-5, -19). Since the line is horizontal, it means that the y-coordinate of any point on the line will be -19.

Therefore, the equation of the horizontal line passing through (-5, -19) is:

y = -19

This is the equation of a horizontal line that lies on the y-axis and intercepts the y-axis at -19.
