Answer:
Given: scale factor k = 3
The coordinate of the given figure is:
(-2 , -1) , (1, -1) , (1, -3) and (-2, -3)
The rule of dilation with scale factor k centered at the origin:-
[tex](x, y) \rightarrow (kx , ky)[/tex]
now, the coordinates of the image of the figure after dilation is:
[tex](-2, -1) \rightarrow (3\cdot -2 , 3 \cdot -1)[/tex] = (-6 , -3)
[tex](1, -1) \rightarrow (3\cdot 1 , 3 \cdot -1)[/tex] = (3 , -3)
[tex](1, -3) \rightarrow (3\cdot 1 , 3 \cdot -3)[/tex] = (3 , -9) and
[tex](-2, -3) \rightarrow (3\cdot -2 , 3 \cdot -3)[/tex] = (-6 , -9)
You can see the image as shown below in the figure.
