A triangle is dilated with the resulting image appearing half as large as the original. Which rule best represents this dilation? A. (x, y) (2x, 2y)

B. (x, y) (.5x, 2y)

C.(x, y) (x-.5, y-.5)

D. (x, y) (.5x, .5y)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
