Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What does it mean for equations to be in standard form?

Back

It means that the equations are arranged so that all variables are on one side and constants are on the other.
