Answer:
y = 3x + 6
Step-by-step explanation:
Since the line is parallel, it has the same slope -- 3
y = 3x + b, sub point (1, 9)
9 = 3(1) + b
9 = 3 + b
b = 9 - 3
b = 6
y = 3x + b -- y = 3x + 6
Multiply then add and then subtract
The soulution of the equation is
x=30
The scale factor of the dilation is

.
Notice how one unit of Q'P' can take up 3 units of QP.
