Properties of Horizontal Lines
Equation of Horizontal Line always takes the form of y = k where k is the y-intercept of the line. For instance in the graph below, the horizontal line has the equation y = 1 As you can see in the picture below, the line goes perfectly sideways at y = 1.
Example 1 of a Vertical Line
Equation: y = 1
