Set 1: Linear Functions (Intermediate)

Choice A is correct. Choice A is the correct answer. Check for coincident lines. 1. Equation 2: Divide by 2 $\rightarrow 2 x + y = 5$. 2. Comparison: It is identical to Equation 1. 3. Result: Same line $\rightarrow$ Infinite solutions. Strategic Tip: If one equation is a multiple of the other, they are the same line. Choice B is incorrect because they touch everywhere. Choice C is incorrect because they are not distinct. Choice D is incorrect because linear systems never have exactly two solutions.
