156 views

To find the rule of a horizontal line, identify the _y-coordinate_ of any point on the line. The equation will be in the form y = c, where c is the y-coordinate value. For instance, if the line passes through the point (3, 5), the rule is y = 5.

FAQs & Answers

  1. What is a horizontal line in mathematics? A horizontal line is a straight line that runs left to right across the page, characterized by a constant y-value for all points on the line.
  2. How do you graph a horizontal line? To graph a horizontal line, plot several points that share the same y-coordinate and connect them with a straight line.
  3. What is the formula for a horizontal line? The formula for a horizontal line is written as y = c, where c is the specific y-coordinate value.
  4. Can a horizontal line have a slope? No, a horizontal line has a slope of zero, meaning it does not rise or fall as it moves left to right.
