Which equation will give a coincident line with 2x + 5y = 13?

Answer and explanation

Correct answer: 4x + 10y = 26

The governing concept is equivalence of linear equations. Two equations represent coincident lines when all three corresponding coefficients, including the constant term, are multiplied by the same non-zero number. Multiplying 2x + 5y = 13 by 2 gives 4x + 10y = 26, exactly the equation in option A. Dividing that equation by 2 returns the original equation, so both equations have every point in common and produce the same graph. Option B has the wrong constant, so it represents a parallel line. Option C keeps the left side but changes the constant, also producing a distinct parallel line. Option D changes the coefficient of y and is not an equivalent equation. Hence A is the only correct choice.
