Answer:
16:12
Step-by-step explanation:    
                    (4+12)=16
16/4 = 4
4x3=12
     Another method:
4---------3
16-------x
Cross multiplication
4x=16x3
4x=48
x=12
 
        
             
        
        
        
(13/3)^3 or (13/3)•(13/3)•(13/3)
        
             
        
        
        
Consider what the slope of this line would be. Slope is rise/run; this line rises 7 (5 - (-2)) and runs 0 (0 - 0). This means that the slope would be 7/0. Dividing by zero is not possible, therefore, it cannot be written in slope-intercept form.
