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

Explanation

Three or more points are said to be collinear if they lie on a straight line.


Let `A(x_1, y_1) = (x, y)`, `B(x_2, y_2) = (1 , 2)` and `C(x_3, y_3) = (7, 0)`


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


Area of a triangle = `1/2 [x_1 (y_2 - y_3) + x_2 (y_3 - y_1) + x_3 (y_1 - y_2)] `....(1)
