are .
Show
that
collineaer
or
not.​

Answer 1

Answer:

To show that the points  are colllinear if we put these in the triangle formulae and the ans is zero then they are colllinear.

triangle formulae-$1/2(x1(y2-y3)+x2(y3-y1)+x3(y1-y2))$

Step-by-step explanation:

=1/2(3(-3-(-2))+2(-2-2)+(-3)(2-(-3))

=1/2(3(-3+2)+2(-4)-3(2+3))

=1/2(-3-8-15)

=1/2(-26)

=-13
