Answer: 
<h3> f^−1(x) = x + 7</h3>
Step-by-step explanation:
Replace f(x) with y. y = x − 7
Interchange the variables.  x = y − 7
Solve for y.  y = x + 7
Solve for y and replace with f^−1 (x).  f^−1(x) = x + 7
I hope this helps have a great day :)
 
 
        
             
        
        
        
Answer:
y-7=1/4(x+5)
Step-by-step explanation:
y-3=-4(x+2)
y=-4x-8+3
y=-4x-5
-----------
y-y1=m(x-x1)
y-7=m(x-(-5))
y-7=m(x+5)
perpendicular means negative reciprocal of the slope,
so the slope will be 1/4
y-7=1/4(x+5)
