Set 13: Linear Functions

Choice A is correct. 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.
