A pair of linear equations whose lines coincide has:
AInfinitely many solutions
BExactly one solution
CNo solution at all
DExactly two solutions
Answer & Solution
Correct answer: A. Infinitely many solutions
1. Every point on the line satisfies both.
2. One equation is a multiple of the other.
3. So there are infinitely many solutions.
