The condition $\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq\dfrac{c_1}{c_2}$ corresponds to lines that are:
Aintersecting (unique solution)
Bperpendicular
Cparallel (no solution)
Dcoincident (infinite solutions)
Answer & Solution
Correct answer: C. parallel (no solution)
a₁/a₂ = b₁/b₂ ≠ c₁/c₂ gives parallel lines and no solution.
