So you gotta change the second one to slope int form and it will become -3y=18x-54 which means that it's A because parallel lines can't be parallel if the slopes are different. (pretty sure this is right but who knows)
A = b√x+c
a/b = √x+c
(a/b)^2 = x + c
(a/b)^2 - x = c
The scale ratio of a point A to another point B is the division of the length of B by the length of A. The best equation that models the situation is: 
The page dimension is:


The length and the width of Uche's book are equal; this means the pages of Uche's book have the shape of a square
The margin of 0.75 on either sided means the usable dimension is:

The dimension of India is:


The longest side in India's dimension is:

From Uche's book, the longest dimension is:

So, the scale equation is:
k * longest length of Uche's book = longest side of India
This gives:
