1, 2, 5 on Ed

Step-by-step explanation:

Answer 2

Answer:

True options:

$D_{O,2} (x,y) = (2x, 2y)$

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 $D_{O,2} (x,y).$ This dilation has the rule

$(x,y)\rightarrow (2x,2y)$

So,

$S(-1,1)\rightarrow S'(-2,2)\\ \\Q(-3,3)\rightarrow Q'(-6,6)\\ \\R(2,4)\rightarrow R'(4,8)$

True options:

$D_{O,2} (x,y) = (2x, 2y)$

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).
