Question

what is the main characteristic of the standard form of an equation? it has no fractions it is always positive it includes only integers it has a constant slope

Explanation:

The standard form of a linear equation (e.g., \(Ax + By = C\) for linear) typically has integer coefficients with no fractions, and \(A\) is non - negative. "It has no fractions" is a key characteristic. "It is always positive" is incorrect as coefficients can be negative (though \(A\) is often made non - negative by convention, the equation itself isn't always positive). "It includes only integers" is not strictly true as coefficients can be rational numbers but are usually expressed as integers by clearing fractions. "It has a constant slope" is for slope - intercept form, not standard form.

Answer:

It has no fractions
