Ok so A is the same as the square root of 4b+c but all of the numbers and the answer have to be prime numbers
        
             
        
        
        
So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b
the slopt inercetp form is y=-x-1
        
                    
             
        
        
        
1. (2x + 1)(x - 7)
2. -x - 4
3. -31x -35
4. 57x + 112
5. (-x) (-x)
        
             
        
        
        
380/14= 27.14 miles per gallon
27.14/2=13.57 miles
they wont reach the gas station
