Question

find the relationship between x and y if the points (x, y),(3,2),(7,7) are collinear​

Answer 1

Answer:

I don't know long.x

Xy(2.6.5)X+y{y}²

Answer 2

Answer:

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

(x

⟹

[x(2−0)+1(0−y)+7(y−2)]=0

⟹

[2x−y+7y−14]=0

⟹

1

[2x+6y−14]=0

⟹2x+6y−14=0

⟹x+3y−7=0

Hence this is the required relation between x and y.
