Standard Form for Linear Equations - Definition & Examples

To get the equation $$3y=\frac{7}{3}x+3$$ in standard form, $$7x-9y=9,$$ which sequence of steps could you use? Select all choices that work.

• I. Multiply the equation by $3$.
• II. Subtract $\frac{7}{3}x$ from both sides.
• III. Multiply the equation by $-1$ and swap the order of the $x$ and $y$ terms.
• IV. Subtract $7x$ from both sides.
