Given conditions are :
In 1980's, a typical middle-income household earned=  $34,757
In 2009, a similar middle-income household earned= $38,550
And we have to find relative increase in income for these households from 1980 to 2009. 
So first we will find the total increase in amounts. 

Relative increase = 
= 10.91% or rounding it off we get approx 11%.
Hence, the answer is 11%.

It would be 1/5 because the line is going in a positive direction and all you have to do is pick to points and do rise/run
        
                    
             
        
        
        
To determine which of the choices is lies on the line represented by the equation, 2x + 5y = 4, substitute the values of the abscissas to the x of the equation and solve for y. Evaluate if the y calculated is equal to the ordinate of the ordered pair. Calculations are shown below.
A. (7, -2)       ; 2(7) + 5y = 4     ;       y = -2      ; EQUAL
B. (0,-1)        ; 2(0) + 5y = 4     ;       y = 0.8    ; NOT EQUAL
C. (0,1)         ; 2(0) + 5y = 4     ;       y = 0.8    ; NOT EQUAL
D. (3, -2)       ; 2(-3) + 5y = 4    ;       y = 2       ; NOT EQUAL
Thus, the answer is letter A. (7, -2)
