Please help with the question

Answer 1

Coordinates of the triangle ABC:

A(-2,2).

B(2,1)

C(-1,-2).

And the coordinates of the dilated triangle A'B'C':

A'(-4,4)

B'(4,2)

C'(-2,-4).

We can clearly see that each x and y-coordinate of triangle ABC is being multiplied by 2 to get the coordinates of triangle A'B'C'.

Therefore, triangle ABC is being dilated by a scale factor of 2.
