sergij07 [2.7K]

Answer:

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:

The explanations are as follows

As we can see from the attached figure that the ΔQ'R'S' is dilated i.e transformation is made or change in size

Now

Based on

(x,y) = (2x,2y)

The intercepts are as follows

For S

(-1,1)  = (-2,2)

For Q

(-3,3) = (-6,6)

For S

(2,4) = (4,8)

Based on this we can say that the three above options are correct
