Answer:
The y-coordinate of B' is equal to 2
Step-by-step explanation:
step 1
Find the distance of AB
step 2
Find the length of A'B'
Multiply the length of AB by the scale factor

step 3
Find the midpoint AB


step 4
<em>Find the x-coordinate of B'</em>
The x-coordinate of B' is equal to the x-coordinate of midpoint plus the semi distance A'B'

<em>Find the y-coordinate of B'</em>
The y-coordinate of B' is equal to 2 (because is a horizontal line)
Answer:A
Step-by-step explanation:
You use the equation:
m= (y2-y1) ÷ ( x2-x1)
