I believe the answer is 1.2
        
                    
             
        
        
        
You'd use the equation y2-y1/x2-x1
0-(-3)/-7-5 = 3/-12 = -1/4
So -1/4 would be the slope
m= -1/4
        
             
        
        
        
 The answer would be 4 weeks and the total be $280. If you plug in 4 for Carly, you get $280 and if you plug in 4 for Janiya, you also get $280
