X^2 - 9x + 18
factors of 18: 1*18, 2*9, 3*6, 
the sums of the factors: 19, 11, 9
the positive 18 tells us both factors have the same sign, the negative 9 tells us they are both negative
(x - 3)(x - 6)

The first one shown, 400/2, is showing the point on the graph where she walks 400 ft in 2 minutes. In order to find the next proportion, you just have to look two minutes over which in this case is 800 ft for 4 minutes... written 800 over 4.
        
             
        
        
        
Call u the cost per uniform. 
Since each of the 15 players gets one uniform and one basketball, we can make the following equation: 
15u + 15(9) = 420
Solve this equation to get u=285/15= $19
