Equations of horizontal and vertical lines

Horizontal and vertical lines are all around us—think of the horizon stretching across the sky or the towering walls of a building. In math, understanding the equations of these lines helps us describe their positions on a graph. Horizontal lines have the same y-value across all points, while vertical lines share the same x-value. This makes them simple but powerful tools in geometry and algebra! Jump to the questions
