When a line is horizontal, it runs parallel to the x-axis and has a slope of 0. This means there's no vertical change as you move along the line; the y-coordinate remains constant while the x-coordinate varies. Horizontal lines are represented by equations of the form y = c, where c is a constant.

FAQs & Answers

  1. What is the slope of a horizontal line? The slope of a horizontal line is 0 since there is no change in the y-coordinate.
  2. How are horizontal lines represented mathematically? Horizontal lines are represented by equations of the form y = c, where c is a constant.
  3. What are some examples of horizontal lines in real life? Examples include the horizon, the ground, and the surface of a still body of water.
  4. How do horizontal lines relate to coordinate planes? In coordinate planes, horizontal lines run parallel to the x-axis, indicating constant y-values across varying x-values.
