Answer:

Step-by-step explanation:
use y = mx + b
slope(m) =  
 
y-intercept(b) = 3
so,

 
        
             
        
        
        
12.....because there are 4 quarters in  $1
        
                    
             
        
        
        
100-21=79
2859(0.79)^3=1409.598
worth $1409.60
        
             
        
        
        
(X,Y) 0=X and 0=Y if you plug in 0 for X and 0 for Y in Y=8X it will be 0=8(0). 8 times 0 is 0 which is the equation
        
             
        
        
        
Step-by-step explanation:
Scatter plots are dots scattered all over the graph.  I think that this is the easiest graph because all you need to do is put a dot where you want it.
A scatter plot doesn't need any lines, all it needs is dots.
