Question -

Find the relation between x and y if thepoints (x, y), (1, 2) and (7, 0) are collinear.



Answer -

If given points are collinear then area oftriangle formed by them must be zero.

Let (x, y), (1, 2) and (7, 0) are vertices ofa triangle,

Area of a triangle = = 0

[x(2 – 0) + 1 (0 – y) + 7( y– 2)] = 0

  • 2x – y + 7y – 14 = 0
  • 2x + 6y – 14 = 0
  • x + 3y – 7 = 0. Which is required result.
