Answer:

y = -3x + 30

Step-by-step explanation:

First, find the slope using the slope formula:

m = (y2 - y1) / (x2 - x1)

m = (9 - (-3)) / (7 - 11)

m = -12/4

m = -3

Next, find the y-intercept by substituding one of the two points into what the equation is so far:

y = -3x + b

(7, 9)

9 = -3(7) + b

9 = -21 + b

30 = b

Now you have the full equation:

y = -3x + 30

Step-by-step explanation:

$\dfrac{(7n-1)!}{(7n+1)!}=\dfrac{(7n-1)!}{(7n+1)(7n)(7n-1)!}=\dfrac{1}{(7n+1)(7n)}\\\\=\dfrac{1}{49n^2+7n}$
