Question

A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated usi X

the origin as the center of dilation.
Which rule could represent this dilation?
A. (x,y) → (0.5 – x,0.5 - y)
B. (x,y) → (x - 7, y - 7)
C. (x,y) - (x, y)
D. (x,y) → (0.9x, 0.9y)

Answer 1

D). (x, y) --> (0.9x, 0.9y).

Explanation:

You multiply each coordinate to create a dilation . To get a smaller image the cinstant of multiplication is less than 1.

So it is D
