How many solutions are there for x + 3y = 9 and 2x + 6y = 18?

Answer and explanation

Correct answer: Infinitely many

The governing concept is the relationship between the two equations. Multiplying x + 3y = 9 by 2 gives 2x + 6y = 18, which is exactly the second equation. Consequently, both equations represent the same straight line rather than two different lines. Every point lying on that line satisfies both equations, so there are infinitely many common solutions. Therefore option C is correct. Option A would apply to two lines that intersect at one point, option B to distinct parallel lines, and option D is not a possible number of intersections for two coincident or distinct straight lines in this context.
