Find a relation b

Answer :

If the given points are collinear, then the area of triangle formed by these points will be 0

Area of the triangle = [x1 (y2 – y3) + x2 (y3 – y1) + x3 (y1 – y2)


= [x (2 – 0) + 1 (0 – y) + 7 (y – 2)


0 = (2x – y + 7y – 14)


2x + 6y – 14 = 0


x + 3y – 7 = 0


This is the required relation between x and y
