The scale factor of a dilation is the ratio of a length in the image to the corresponding length in the original figure.

This dilation is centred at the origin, so you can find the image by multiplying the x– and y-coordinates by the scale factor.

Multiply the coordinates of point P(^–2, ^–2) by 5. The image is P′(^–10, ^–10).

Now multiply the coordinates of point Q(^–2, 2) by 5. The image is Q′(^–10, 10).

Now multiply the coordinates of points R(1, 2) and S(1, ^–2) by 5. The images are R′(5, 10) and S′(5, ^–10).

The dilated points form a rectangle similar to PQRS.

The scale factor of a dilation is the ratio of a length in the image to the corresponding length in the original figure.

This dilation is centred at the origin, so you can find the image by multiplying the x– and y-coordinates by the scale factor.

Multiply the coordinates of point C(^–9, 0) by 1/3. The image is C′(^–3, 0).

Now multiply the coordinates of point D(^–9, 6) by 1/3.The image is D′(^–3, 2).

Now multiply the coordinates of points E(9, 6) and F(9, 0) by 1/3.The images are E′(3, 2)and F′(3, 0).

The dilated points form a rectangle similar to CDEF.
