Line
A straight path of points that extends forever in two directions. A line doesn’t have any thickness or width. Arrows sometimes show that the line goes on forever in either direction
A line is a one-dimensional, infinitely-extending figure composed of an infinite number of points. In geometry, a line is perceived as a fundamental tool used to construct various geometric shapes and figures. It is represented by a straight line that has no thickness or width and can be described by using two points. These points indicate the direction and length of the line.
In mathematics, lines can be classified based on their slope. A line can have a positive slope or a negative slope. A line with a positive slope rises from left to right, while a line with a negative slope falls from left to right.
Furthermore, lines can intersect, be parallel, or be perpendicular to one another. Parallel lines never intersect and have the same slope, while perpendicular lines intersect at a right angle and have opposite reciprocal slopes.
