Finding the equation of a line through two points is one of the fundamental problems in analytic geometry. This situation comes up in a huge number of exercises and problems, and it forms the basis for the study of parallel and perpendicular lines, families of lines, the distance from a point to a line, and … Read more

The slope is one of the central concepts in analytic geometry. Geometrically, it describes how inclined a line is in the coordinate plane; analytically, it provides essential information for working with a line’s equation. Understanding what slope means and how to calculate it makes it possible to read a line’s equation correctly and to use … Read more
