Ok so what you want to do is replace the n with whatever number is in the parenthesis next to the f
The idea being, the notation is for a "serie" or sequence.
f(n-1) simply means, "the value of the term before the current one", whilst "n" is the current term.

Step-by-step explanation:
slope = y2 - y1 / x2 - x1
(-2,5) (6,5)
5-5/-2-6
0 / -8
slope is 0
kx-4=9
Move -4 to the other side. Sign changes from -4 to +4
kx-4+4=9+4
kx=13
Divide by k for kx and 13
Cross out k and k = 1.
x=13/k
Answer: x=13/k
