Set 2: Linear Functions (Intermediate)

Choice A is correct. Choice A is the correct answer. Interpret the linear model. 1. Model: $y = mx + b$ form. 2. Slope ($m$): The coefficient of the variable (0.$5$). It represents the rate of change. 3. Context: Cost per mile. Strategic Tip: Slope is always a "rate" (something per something). Intercept is the "starting amount". Choice B is incorrect because 10 is the y-intercept (base fee). Choice C is incorrect because $C$ is the dependent variable. Choice D is incorrect because $m$ is the independent variable.
