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.

Answer:

True options:

[tex]D_{O,2} (x,y) = (2x, 2y)[/tex]

Side Q'S' lies on a line with a slope of -1.

The distance from Q' to the origin is twice the distance from Q to the origin.

Step-by-step explanation:

Triangle QRS is dilated according to the rule [tex]D_{O,2} (x,y).[/tex] This dilation has the rule

[tex](x,y)\rightarrow (2x,2y)[/tex]

So,

[tex]S(-1,1)\rightarrow S'(-2,2)\\ \\Q(-3,3)\rightarrow Q'(-6,6)\\ \\R(2,4)\rightarrow R'(4,8)[/tex]

True options:

[tex]D_{O,2} (x,y) = (2x, 2y)[/tex]

Side Q'S' lies on a line with a slope of -1.

The distance from Q' to the origin is twice the distance from Q to the origin.

False options:

QR is longer than Q'R', because QR is twice shorter than Q'R'.

The vertices of the image are closer to the origin than those of the pre-image, because the vertices of the per-image are closer to the origin than those of the image (see attached diagram).
