Step-by-step explanation:
(fog)(x) = f[g(x)]
f(g(x))
f(x-2)
since f(x) = 1 / x
answer: 1/x-2
1/x-2 looks like 1/x but the asymptotes(dips in the graphs) will be at x = 2 since is undefined
A standard line equation takes the form of y=mx+b
m= the slope so we see that 2 is next to x in your example
A) Slope = 2
Perpendicular lines will have the negative reciprocal of the original equation's slope
2 -> -
B) 
The picture isn’t showing up…
That is standard form, if you are looking for the expanded form then it's 6+.2+0.4
