What will be the graph of (2x+4y=10) and (x+2y=7)?

Answer and explanation

Correct answer: Distinct parallel lines

Multiplying the second equation by 2 gives 2x+4y=14, whereas the first equation is 2x+4y=10. Thus, the ratios of the coefficients of x and y are equal, but the ratio of the constant terms is different. Therefore, the two lines are distinct and parallel. Option A is incorrect because coincident lines require all three corresponding ratios to be equal. Exam tip: if a₁/a₂ = b₁/b₂ ≠ c₁/c₂, the lines are parallel and distinct.
