What is the standard form of a linear equation?

The standard form of a linear equation is represented as Ax + By = C. In this format, A, B, and C are integers, and A and B are both not zero. This representation allows you to easily identify the coefficients of the x and y variables and is useful for quickly graphing the line or analyzing its properties such as intercepts.

The other options present different forms of equations. The first option, y = mx + b, represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept. The third option, y = ax^2 + bx + c, represents a quadratic equation, which involves a squared term and describes a parabola rather than a straight line. The last option, Ax^2 + Bx + C = 0, also refers to a quadratic equation in standard form (not linear) and is used to find the roots of a polynomial rather than to describe a linear relationship. Thus, the standard form specifically focuses on the linear relationship captured by Ax + By = C.
