The standard form of a linear equation is Ax By = C, where A, B, and C are constants and x and y are variables. The variables x and y are typically used to represent the horizontal and vertical axes of a Cartesian coordinate system. The coefficients A and B represent the slopes of the x and y axes, respectively, and the constant C represents the y-intercept of the line. The standard form of a linear equation is useful for solving systems of linear equations, graphing lines, and identifying the s
