Choice A is the correct answer. Cover-up method.

1. x-int ($y=0$): $2x = 8 \rightarrow x = 4$.
2. y-int ($x=0$): $4y = 8 \rightarrow y = 2$.

💡 Strategic Tip: Divide the constant term by the coefficients.

Choice B is incorrect because swapped. Choice C is incorrect because ignored coefficients. Choice D is incorrect because sign error.
