Answer:
A. (2,3) 
 It is rather simple the 9 points between a and B 2/3 of that is 6
 
        
             
        
        
        
I assume the x between -11 and 2 is multiply
that would be -22=x+11
x=-33
so there's only one solution.
        
             
        
        
        
Answer:
Overestimate 
Step-by-step explanation:
it would be an underestimate if the number was lower than the actual number but since its larger than it is an overestimation.
hope this helps 
 
        
             
        
        
        
Answer:  Choice A.   4 times
========================================================
Explanation:
We'll be using this formula

to compute the average rate of change (AROC) from x = a to x = b. Note how this is effectively the slope formula because y = f(x).
To start things off, we'll compute the AROC from x = 1 to x = 2.

Do the same for the AROC from x = 3 to x = 4.

The jump from m = 10 to m = 40 is "times 4", which is why choice A is the final answer.
