Answer 2

Yes its sufficient .

How?Steps?

• First rewrite three co-ordinates.
• Find area of triangle through these points.
• Take Area=0 as Colinear points can't be vertices of the triangle .
• Then solve the equation algebraiccally and get x,y

Formula:-

$\boxed{\sf Area\:of\:triangle=\dfrac{1}{2}\mid x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)\mid}$
