Category : JEE Main & Advanced

The straight line is a curve such that every point on the line segment joining any two points on it lies on it. The simplest locus of a point in a plane is a straight line. A line is determined uniquely by any one of the following:

(1) Two different points (because we know the axiom that one and only one straight line passes through two given points).

(2) A point and a given direction.
