Which statement is correct about the graph of the equations (14x+21y=49) and (2x+3y=8)?

Answer and explanation

Correct answer: Lines are distinct parallel

For the two equations, the ratios of the coefficients of x and y are equal: 14/2 = 21/3 = 7. However, the ratio of the constant terms is 49/8, which is not equal to 7. Thus, the two lines have the same slope but different positions, so they are distinct parallel lines. Coincident lines would require all three ratios to be equal. Exam tip: If a₁/a₂ = b₁/b₂ ≠ c₁/c₂, the pair represents distinct parallel lines.
