Answer:
b
Step-by-step explanation:
The slope is positive because as the age increases, the value increases.
 
        
                    
             
        
        
        
The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know): 
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37. 
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
 
        
                    
             
        
        
        
Answer:
reflecting over y just simply means counting the space between the shape and their points to the line and using that same number on the other side for example for the point -4,-4 is 2 spaces from the line then count 2 on the other side
