C would be the right answer!

If you have any more questions please don't be hesitant to ask me:))

Answer:

The correct option is C.

Step-by-step explanation:

It is given that the vertices of a triangle on the coordinate plane are A(0, 0), B(2, 0) and C(0, 2).

If a figure dilated by a factor of k about the origin, then

[tex](x,y)\rightarrow (kx,ky)[/tex]

It is given that triangle ABC was dilated by a factor of 1/3 to create the triangle A'B'C'.

If a figure dilated by a factor of 1/3 about the origin, then

[tex](x,y)\rightarrow (\frac{1}{3}x,\frac{1}{3}y)[/tex]

The vertices of image are

[tex]A(0,0)\rightarrow A'(0,0)[/tex]

[tex]B(2,0)\rightarrow B'(\frac{2}{3},0)[/tex]

[tex]C(0,2)\rightarrow C'(0,\frac{2}{3})[/tex]

The coordinates of triangle A'B'C' are A'(0,0), B'(2/3,0) and C'(0,2/3).

Therefore, the correct option is C.
