Answer:

Step-by-step explanation:

Putting x = 1
=> 
Given that f(1) = 1
=> 
=>
-------------------(1)
Now,
Putting x = 2
=> 
Given that f(2) = 5
=> 
=> 
=>
----------------(2)
Subtracting (2) from (1)

For b , Put a = 9 in equation (1)

Y= -x+4
2x+2(-x+4)=8
2x-2x+8=8
8=8
x+y= 4
2x+2y= 8
-2x-2y= -8
2x+2y= 8
0=0
the answer is b inconsistent
