b = 5
Step-by-step explanation:
Answer:
-5
-3
-2
Rule: Subtract 2 from the input value
Step-by-step explanation:
Examine the pattern of the input and the corresponding output for the two given ordered pairs:
Input -2 → Output -4
Output - Input = -4 - (-2) = -2
Input 1 → Output -1
Output - Input = -1 - 1 = -2
Therefore to get the output value (y-value), we subtract 2 from the input value (x-value).

As the rule for the function is the subtract 2 from the input value to get the output value, we can write this as:
Output = Input - 2
or as an equation: 
1/3 - 2/9 - 1/3
= -2/9
(Decimal: -0.222222)
Ends up=( K+5)1/2 -2
ends up=K/2+2.5-2=K(.5) + .5
