2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)

The most likely answer is B.
Highlighting the corresponding parts from the original in the copy is just coloring in the parts of the copy that have the same scale, for example, if the center of the scaled copy is one unit, the original could be 3 units.
Answer:
(-(23/3), -(11/3))
Step-by-step explanation:
x=y-4
2x-5y=3
=====
2x-5y=3
2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]
2y - 8 -5y = 3
-3y = 11
y = -(11/3)
y = -3 2/3
Use this in the 1st equation to find x:
x=y-4
x=-(11/3)-4
x = -(11/3)-(12/3)
x = -(23/3)
x = -7 2/3
