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: $2x - 5(0) = 10 \rightarrow 2x = 10$.
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.
