Hello : 
<span>the linear function has form : y = ax </span>
        
                    
             
        
        
        
The answer is 2 and negative 9
        
             
        
        
        
Answer:
Dependent variable: y because you get the points by doing the quiz.
Independent variable: x because you don’t know how many questions you answered correctly.
Total points you score: Unknown until you know how many you got right also the same as y.
Number of questions you answer correctly: Unknown until you get your paper back, also the same as x.
 
        
                    
             
        
        
        
Answer:
yes
Step-by-step explanation:
A relation is a function in which for each input there is only one output.
In a relation, y is a function of x.
Now we look at the mapping
For input 6, -1 is the output
for input -1, 2 is the output
for input 4, 3 is the output
for input 0, 3 is the output
For each input , there is an output. Input is not repeating. Input is occurring only once. 
So this relation is a function.
 
        
             
        
        
        
Answer:
Set the two equations equal to each other if you want me to solve tell me. 
So.... 15x+10=16x+3
-15                  -15
10=1x+3
-3
7=x
