The points (1, 5), (2, 3) and (minus 2, minus 11) are examined to check whether they are:
AConcentric
BCongruent
CConjugate
DCollinear
Answer & Solution
Correct answer: D. Collinear
1. An area of zero would settle it.
2. The question is whether one line holds all three.
3. They are being checked for being collinear.
