• To eliminate the fractions

• To simplify the equation

• To balance the equation

What is the final form of the equation after converting y = 1/3x - 2/5 to standard form?

• 5x - 15y = 6

• -5x + 15y = -6

• 5x + 15y = -6

• 5x - 15y = -6

What is the correct order of terms in standard form?

• Ax + By = C

• By + Ax = C

• C = Ax + By

• Ax = By + C

How do we ensure the A value in standard form is not negative?

• Multiply the entire equation by -1

• Add a positive constant

• Divide the entire equation by -1

• Subtract a negative constant
