Linear equation( Point–slope form)


A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable. The point-slope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y − y1) is proportional to the difference in the x coordinate (that is, x − x1). The proportionality constant is m (the slope of the line).
