Choice A is the correct answer. Calculate rise over run from the graph.

1. Points: $(0, 2)$ and $(3, 0)$.
2. Rise: From $y=2$ down to $y=0$ is a change of $-2$.
3. Run: From $x=0$ right to $x=3$ is a change of $+3$.
4. Slope: $\frac{\text{Rise}}{\text{Run}} = \frac{-2}{3} = -\frac{2}{3}$.

💡 Strategic Tip: If the line goes down from left to right, the slope MUST be negative.

Choice B is incorrect because it flips rise and run. Choice C is incorrect because it misses the negative sign. Choice D is incorrect because it flips rise/run and misses the sign.
