Choice A is the correct answer. Use $y = mx + b$ to find $b$.

1. Substitute: $5 = 3(2) + b$.
2. Simplify: $5 = 6 + b$.
3. Solve: $b = -1$.
4. Equation: $y = 3x - 1$.

💡 Strategic Tip: Or use point-slope form: $y - 5 = 3(x - 2) \rightarrow y = 3x - 6 + 5 \rightarrow y = 3x - 1$.

Choice B is incorrect because it assumes the y-coordinate is the intercept. Choice C is incorrect because it adds instead of subtracts ($5+6$). Choice D is incorrect because it swaps slope and x-coordinate.
