Correct Question:
P(1 , 1), Q(- 2 , 7) and R(3 , - 3)bshow the points are collinear.
Answer:-
We have to prove that P(1 , 1) , Q (- 2 , 7) & R (3 , - 3).
We know that,
If three points are collinear then the area of the triangle formed by them will be 0 (zero).
→ Area of ∆PQR = 0 sq.units.
We know,
Area of a triangle with vertices is :
Let,
Hence,
Hence, Proved.
