We know that ,
If the area of a Δ is 0 units , then its vertices will be collinear . So ,
The area of triangle formed by the vertices A(1,-1) , B(4,1) , and C(-2,-3) , by using the above formula , is given by
Therefore , the given points are not collinear
The area of triangle formed by the vertices D(1,-1), E(2,3), and F(2,0) , by using the above formula , is given by
Therefore , the given points are not collinear
The area of triangle formed by the vertices G(1,-6), H(3,-4), I(4,-3) , by using the above formula , is given by
Therefore , the given points are collinear
