Math 1300 Section 2.4 Notes 5 Equations of a Line Forms of Equations: 1. The standard form of a linear equation is given by C By Ax = + where A and B cannot both be equal to zero. Example: 5 4 2 = + y x 2. The point-slope form of a linear equation is given by ) ( 1 1 x x m y y - = - where m is the slope and the line passes through the point ( x 1 , y 1 ). Example:
