A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated using the origin as the center of dilation. Which rule could represent this dilation?

HINTS:

1. Dilation means the shape is made larger or smaller by multiplying a measurement of the shape by a scale factor.

2. In order to find the NEW measurement, you need to multiply by the scale factor

3. Since this polygon is becoming smaller, you need to multiply by a scale factor smaller than 1.

( x , y ) (0.5 - x , 0.5 - y )

( x , y ) ( x - 7, y - 7)

( x , y ) ( 5/4
x , 5/4
y )

( x , y ) (0.9 x , 0.9 y )
