[Free] Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First, she found three points on the graph to be $(-1,-4),(0,-3)$, and $(2,5)$. Next, she determined the rate of change between the points $(-1,-4)$ and $(0,-3)$ to be $\frac{-3-(-4)}{0-(-1)}=\frac{1}{1}=1$ and the rate of change between the points $(0,-3)$ and $(2,5)$ to be $\frac{5-(-3)}{2-0}=\frac{8}{2}=4$. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? A. The points $(-1,-4),(0,-3)$, and $(2,5)$ are not all on the graph. B. The expressions $\frac{-3-(-4)}{0-(-1)}$ and $\frac{5-(-3)}{2-0}$ both equal 1. C. She miscalculated the rates of change. D. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.
