Which statement is correct about the graph of (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 lines have the same slope but different positions, so they are distinct parallel lines. Exam tip: when a₁/a₂ = b₁/b₂ ≠ c₁/c₂, the pair represents distinct parallel lines.
