Answer:
Not collinear
Step-by-step explanation:
Let the points be A(1, 5), B(2, 3), and C(- 2,-11).
AB = √(1 - 2)^2 + (5 - 3)^2 = √1 + 4 = √5
BC = √(2 - (-2)^2 + (3 - (-11)^2) = √16 + 196 = √212
CA = √(1 - (-2))^2 + (5 - (-11))^2 = √9 + 256 = √265
Since, AB + BC ≠ CA
Hence, the given points are collinear.
