Answer:
![\large\boxed{B.\ y-3=-5(x-6)}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BB.%5C%20y-3%3D-5%28x-6%29%7D)
Step-by-step explanation:
The point-slope form of an equation of a line:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
m - slope
(x₁, y₁) - point
We have the slope m = -5 and the point (6, 3). Substitute:
![y-3=-5(x-6)](https://tex.z-dn.net/?f=y-3%3D-5%28x-6%29)
![(\frac{x + 1}{x} ) ^{2} \\ = \frac{ {(x + 1)}^{2} }{ {x}^{2} } \\ = \frac{ (x + 1)(x + 1) }{ {x}^{2} } \\ = \frac{ {x}^{2} + 2x + 1}{ {x}^{2} }](https://tex.z-dn.net/?f=%20%28%5Cfrac%7Bx%20%2B%201%7D%7Bx%7D%20%29%20%5E%7B2%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B%20%7B%28x%20%2B%201%29%7D%5E%7B2%7D%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%5Cfrac%7B%20%28x%20%2B%201%29%28x%20%2B%201%29%20%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20%5C%5C%20%3D%20%5Cfrac%7B%20%7Bx%7D%5E%7B2%7D%20%20%2B%202x%20%2B%201%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20)
