The First two coefficients are positive because they are on the positive side of the y-axis. 
The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.
 The coefficient with the greatest value would be D
 
        
             
        
        
        
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
First we have parentheses.
-4(3 - 1) + 2
3 - 1 = 2
-4(2) + 2
We have no exponents so go on to multiplication
-4(2) + 2
-4 * 2 = -8
-8 + 2
No division so go to addition
-8 + 2
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number  (disregarding the signs). In this case the largest number is 8 and its sign is negative. Your answer will have a negative sign.
-6
