Answer:
The second option is the answer.
Step-by-step explanation:
The center of a dilation makes all the corresponding vertices coincide at one point if we draw a straight line including that pre image and new image point. All coordinates correspond about Point C. So the first two options are the viable answers.
The blue triangles right side measure is 10 while the smaller triangle right side measure is 5. This means the scale factor is
So our scale factor is 2.
The second option is the answer.

Answer:
first number=2
second number=-5
Step-by-step explanation:
first number= a
second number= b
we have the following equations
7a+3b=-1 equation 1
a+b=-3 equation 2
using equation 2 we have
a=-3-b
using equation 1 we have
7(-3-b)+3b=-1
-21-7b+3b=-1
-4b=20
b=-20/4=-5 = second number
a+(-5)=-3
a-5=-3
a=-3+5
a=2= first number
