Answer:
but its right
Step-by-step explanation:
 
        
                    
             
        
        
        
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:

That means that the slope is -1.
ANswer:

 
        
                    
             
        
        
        
We know, 1 ounce = 29.57 ml
so, 64 ounces = 1892.71 ml
so, remaining drink would be: 1892.71-700 = 1192.71 ml
