I think this is right... sorry if not
 
        
                    
             
        
        
        
since the graph has direct variation as data in x axis increases y also increases.
so we need to find how many miles travelled per galloon .
 we distance travelled per gallon =total distance travelled/galoons of fuel used.

for part b) slope=rise/run



slope of the graph is 2 
 
        
             
        
        
        
X=7 
100-30=70 
70/10
x=7
hope this helps
