Step-by-step explanation: The question tells us that the population decreases by 1/4 every single year. That means, since 1/4 equals .25, the population decreases by 25% every year :)
 
        
             
        
        
        
Answer is A and B
A) -7.13 < -0.8
B) -0.86 < -0.8
C) -0.79 > -0.8
D) 0.846 > -0.8
        
                    
             
        
        
        
How do we graph anything? Make a table of values for x and y and then plot each point. After plotting each point on the xy-plane, connect each point with a straight line or curve (depending on the function). 
In this case, we must first isolate y.
y = (-4/3)x + 8y
y - 8y = (-4/3)x
-7y = (-4/3)x 
y = (-4/3)x ÷ (-7)
y = (4/21)x
Now follow the steps above.
