anonymous · Answer

The standard form of an equation is Ax + By = C (the capitol letters of this formula represent numbers)

Let me tell you some rules about these equations in standard form...
A B and C are integers (positive or negative whole numbers)
No fractions and no decimals in standard form.
Traditionally the Ax term is positive.

Now just by following these rules, you can find the answer. Good luck :)
