👉 In mathematics, the term "subtangent" is used to describe a specific type of line segment that can be drawn between two points on a plane. This line segment is perpendicular to the x-axis and has its endpoints at the same distance from the origin as the corresponding endpoints of a straight line. The slope of this line segment is -1, meaning it is slanted downward. For example, if we draw a line segment that starts at (2, 3) on the y-axis
