Answer: Y=-1/4x+2
Slope: -1/4
Y intercept: 2
        
             
        
        
        
14/16= .875 the answer is 87.5%
        
             
        
        
        
2.3= 2.03 so there for it is equal
        
             
        
        
        
12+18=30 so together they have $30.00 in all.
