Transformation Rules

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

• A. (x, y) --> (1.5 - x, 1.5 - y)

• B. (x, y) --> (x - 10, y - 10)

• C. (x, y) --> (7/3x, 7/3y)

• D. (x, y) --> (0.75x, 0.75y)
