The equation of a line in standard form is represented as Ax + By = C. In this format, A, B, and C are constants, and both A and B should ideally not be zero simultaneously. The equation can provide insights into the x-intercept and y-intercept of the line easily.

This format is especially useful for quickly identifying the coefficients of x and y, which relate directly to the slope of the line when manipulated into slope-intercept form (y = mx + b). While the other forms listed may represent equations of lines, only the standard representation is formally known as the standard form.

In contrast, the other options do not fit the standard form definition. For example, y = mx + b is specifically the slope-intercept form, which highlights the slope and y-intercept but does not express the equation as a polynomial equal to a constant. Each format serves its purpose in different contexts, but when it comes down to standard form, Ax + By = C is the definitive representation.
