Answer:
It's the second one I believe, because it's not a straight line, and nearly all functions have curved lines

Answer: a=8 and b=1
Step-by-step explanation:
If x represents the paddling speed, and y represents the speed of the current.
Then Relative speed in upstream =x-y
Relative time in downstream=x-y
When she paddles upstream then distance covered by her=
⇒8=(x-y)2 or 2(x-y)=8
Thus we get, a=1
When she paddles downstream then distance covered by her=
⇒8=(x+y)1 or 1(x+y)=8
Thus we get b=1
 
        
                    
             
        
        
        
The answer is B. 5 degrees celcius
The formula is 
(temprature in celcius)=(temprature in fahrenheit -32) *5/9
or
Temprature in celcius=( temprature in fahrenheit-32) * 1.8
        
             
        
        
        
Hello, sorry if this seems a bit odd, it’s a common method though. Hope you can understand this. Thanks
