If the two lines of a pair of linear equations are coincident (same line), the pair has
Ano solution
Ba unique solution
Cinfinitely many solutions
Dtwo solutions
Answer & Solution
Correct answer: C. infinitely many solutions
1. Coincident lines lie exactly on top of each other.
2. Every point on the line satisfies both equations, so there are **infinitely many solutions**.
3. Their coefficients satisfy a₁/a₂ = b₁/b₂ = c₁/c₂.
