What is line definition?

In geometry, a line is a straight, infinitely long defined path made up of an infinite number of points. A line can be defined as the shortest distance between two points and can extend infinitely in both directions. It can be represented and defined using different methods, including equation, two-point form, slope-intercept form, and normal form. In terms of equation, a line can be defined by the formula y = mx + b, where m is the slope and b is the y-intercept. Lines can also be parallel or intersecting, and they can have different degrees of inclination or slope. The study and analysis of lines are crucial in various areas of mathematics, physics, and engineering.
