Vertical lines are defined by the equation of the form x = a constant, such as x = 5. Since the slope of a vertical line is undefined, you can't use the slope-intercept form (y = mx + b) to represent it. Instead, simply state the constant x value for the vertical line.

FAQs & Answers

  1. What is the equation for a vertical line? A vertical line is represented by the equation x = a constant, like x = 5.
  2. Why can't you find the slope of a vertical line? The slope of a vertical line is undefined because it does not have a rise over run, making it impossible to calculate.
  3. How does a vertical line appear on a graph? On a graph, a vertical line appears straight up and down, crossing the x-axis at its constant value.
