Question

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

Answer 1

Given $(x,y)$;  $(1,2)$ and $(7,0)$ are collinear points.

$x(2-0)+1(0-y)+7(y-2)=0$

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

$2x+6y-14=0$

$x+3y-7=0$

This is the relation between $x$ and $y$.

Answer 2

Given (x,y) ; (1,2) and (7,0) are collinear points.

x(2-0)+1(0-y)+7(y-2)=0

2x-y+7y-14=0

2x+6y-14=0

x+3y-7=0

This is the relation between x and y .
