2. draw the image of rst under the dilation with scale factor 2/3 and center of dilation (1,-1). label the image rst .

From the graph: we have the coordinates of RST i.e,

R = (2,1) , S = (2,-2) , T = (-1,-2)

Also, it is given the scale factor and center of dilation C (1,-1)

The mapping rule for the center of dilation applied for the triangle as shown below:

or

or

Now,  

for R = (2,1)  

the image R' = or

⇒ R' =  

For S = (2, -2) ,

the image S'=   or

⇒ S' =

and For T = (-1, -2)

The image T' =   or

⇒ T' =

Now, label the image of RST on the graph as shown below in the attachment:

boxplot e is the answer

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
