Determine the points are collinear (1,2) (2,3) and (-2,-11)

Given:

The three points are (1,2), (2,3) and (-2,-11).

To find:

Whether the given points are collinear.

Solution:

Let as consider the three points are A(1,2), B(2,3) and C(-2,-11).

If these three points are collinear, then area of must be 0.

Area of ,

Therefore, the given points are not collinear.
