Set 3: Linear Functions (Intermediate)

Choice A is correct. Choice A is the correct answer. Set $y=0$ to find the x-intercept. 1. Method: The x-intercept occurs where $y = 0$. 2. Substitute: $2x - 5(0) = 10 \rightarrow 2 x = 10$. 3. Solve: $x = 5$. Strategic Tip: Cover up the y-term ($2x = 10$) to find the x-intercept instantly. Choice B is incorrect because it is the y-intercept. Choice C is incorrect because it divides 10 by 5 incorrectly or confuses variables. Choice D is incorrect because it confuses signs.
