I have found the options elsewhere and they are as follows:
the slopes must be positive
the slopes must be negative
their slopes are equal
the slopes are opposite reciprocals.
From the choices, I think the correct answer would that their slopes are equal since they are parallel lines and never intersect.

Answer: 5x - 9 = 6
Step-by-step explanation:
x = 3
2(3) - 8 -= 5 --> 6 - 8 =5 (false)
9(3) + 4 = -31 --> 27 + 4 = -31 (false)
6(3) - 9 = 57 --> 18 - 9 = 57 (false)
5(3) - 9 = 6 --> 15 - 9 = 6 (true)
First you must know that f(x) means the same thing as y so...
y = 9x - 8
To find the inverse switch the places of x and y and solve for y
x = 9y - 8
x + 8 = 9y
^^^That means the answer is A!
Hope this helped!

Answer:
f(x) = (x + 3)² - 14
Step-by-step explanation:
f(x) = x² + 6x - 5
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 5
= (x + 3)² - 14 ← in vertex form
The answer is X = 4, 2
You can even plug those in for X to check your answer.
