Answer:
y=1/2x-3
Step-by-step explanation:
I am pretty sure that it is the first choice because it is the only one that is true
ANSWER
B' has coordinates (16,14).
EXPLANATION
The given coordinates of square ABCD are :
A (2,7) , C (8,1),D (2,1)
In order to form a square, the coordinates of B should be: (8,7)
The mapping for dilation with a scale factor 2, about the origin is

This implies that:

When we simplify we get:

Hence B' has coordinates (16,14).
Answer:
Yes
Step-by-step explanation:
because if you add that and then you subtract that you get that answer
