WebJan 3, 2024 · Equations of horizontal and vertical lines involve identifying the slope and y-intercept based on known information. Learn how these are formed for both types of … WebThus, the equation is y = 2. Vertical Lines Similarly, in the graph of a vertical line, x only takes one value. Thus, the equation for a vertical line is x = a, where a is the value that x takes. Example 3: Write an equation for the following line: Graph of a Line Since x always takes the value 2 = , the equation for the line is x = .
