To Identify the equation as horizontal or vertical line, use the following formulas.

- Horizontal Line: \( y = b \), where the line crosses the \( y \)-axis at \( b \) is the \( y \)-coordinate. The \( y \)-value is the same for every point.
- Vertical Line: \( x = a \), where the line crosses the \( x \)-axis at \( a \) is the \( x \)-coordinate. The \(x \)-value is the same for every point.
