Question

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

Answer 1

Answer:

Step-by-step explanation:

Let the point P(x, y), A(1,2) and B(7,0).

Since, A, P and B are collinear.

Ar(ABC) =>1/2{1(y-0)+x(0-2)+7(2-y)} =0

=>y-0-2x+14-7y=0

=>-2x-6y+14=00

=>2x+6y-14=0

=>x +3y-7=0

This the required relation
