Answer:
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:
Answer:

Step-by-step explanation:
Given

To express as a rational number with 91 on the denominator.
91 ÷ 7 = 13
Thus multiply the numerator and denominator by 13, that is
= 
Comparison of fractions is easiest when they all have a common denominator, in this case we can make them all have a common denominator of 16...
12/16, 9/16, 3/16, 14/16, 6/16 so from least to greatest...
3/16, 3/8, 9/16, 3/4, 7/8
Answer: (3, -2)
Step-by-step explanation:
The solution to the system is where the graphs intersect.
