Triangle qrs is dilated according to the rule do,2 (x, y). what is true about the image △q'r's'? check all that apply. do,2 (x, y) = (2x, 2y) side q's' lies on a line with a slope of -1. qr is longer than q'r'. the vertices of the image are closer to the origin than those of the pre-image. the distance from q' to the origin is twice the distance from q to the origin.

I've never seen the notation DO 2(x,y) but let's assume it means a dilation of a scale factor of 2 around the origin.

Then it's true that DO,2(x,y)=(2x,2y)

We're not given any information about QRS so we don't know the slope of its sides; dilation by two won't change those slopes.

The vertices will be twice as far from the origin on the image than on the preimage, that's what dilating by two means.

The distance OQ' = 2 OQ; that's what this dilation does.
