Convert gallons to ounces 
There 128 ounces in 1 gallon
So you would multiply 
(214gal)*(128oz/1gal)=27392 ounces 
27392oz / 4 oz = 6848 cups
        
             
        
        
        
Answer: (-2,4)
Step-by-step explanation:
When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
