1. **State the problem:** We are given the equation $\frac{y}{x} = 2$ and need to understand or solve it. 2. **Understand the equation:** The equation $\frac{y}{x} = 2$ means that $y$ is twice $x$. 3. **Rewrite the equation:** Multiply both sides by $x$ to isolate $y$: $$y = 2x$$ 4. **Explain the step:** We multiplied both sides by $x$ to cancel the denominator on the left side. This is valid as long as $x \neq 0$. 5. **Final expression:** The relationship between $y$ and $x$ is linear, given by: $$y = 2x$$ This means for any value of $x$, $y$ is double that value.
