Ainconsistent
Bparallel
Cundefined
Dconsistent
Answer & Solution
Correct answer: D. consistent
1. Pairs are classified by whether a solution exists.
2. A pair with one or more solutions is **consistent** (intersecting or coincident lines).
3. A pair with no solution is inconsistent (parallel lines).
