In earlier classes, you have read about lines in the Euclid geometry section. That is just an introduction but now we go in depth of lines and its various aspects. Concepts of lines are very essential to know about conics and 2d-3d geometry, which we will discuss later. This chapter consists of basics of 2d geometry, shifting of origin, slope of line, angle between two lines, various forms of equation of line point - slope form slope intercept form, two points form, intercept form, normal form, etc., general equation of line, distance of a point from a line, equation of family of lines.
