Set 15: Linear Functions (Advanced)

Choice A is correct. Choice A is the correct answer. Isolate $y$ to find the slope. 1. Equation: $2y = 8 x - 6$ 2. Divide by 2: Divide every term by 2 to get $y$ by itself. $\frac{2 y}{2} = \frac{8 x}{2} - \frac{6}{2}$ 3. Simplify: $y = 4 x - 3$ 4. Identify Slope: The coefficient of $x$ is 4. Strategic Tip: You cannot read the slope directly until the equation is in $y = ...$ form. Choice B is incorrect because it takes the coefficient of $x$ before isolating $y$. Choice C is incorrect because it is the coefficient of $y$. Choice D is incorrect because it is the y-intercept.
