Answer:
1 and 1/30 gallons
Step-by-step explanation:
First, convert all the fractions to a common denominator. I'm choosing 30.
1/3=10/30  1/5=6/30  1/2=15/30
Now, you can add them together to get 31/30, so a little more than a gallon
 
        
             
        
        
        
Slope-intercept form is y=mx+b. It looks like you already have most of the equation there. Just rearrange a little. From what I can tell, you have y=1 - 1/2x. Just move the negative 1/2x in front of the 1. You'll get y= -1/2x + 1. Hope this helped!
