It would be 0 because as you go along it doesn't go up but keeps moving. An undefined slope is up and down/vertical.

600,00,000 40,000,000 3,000,000 60 2 is this what our asking
        
             
        
        
        
Answer:
Every 18 miles he uses 3 gallons
divide this:
18 ÷ 3 = 6 miles per gallon
30 miles = 30 ÷ 6 = 5 gallons
7 gallons = 7 x 6 = 42 miles
48 miles = 48 ÷ 6 = 8 gallons
10 gallons = 10 x 6 = 60 miles
Hope this helps :D
 
        
                    
             
        
        
        
1) m - 7 < 6
 Add 7 to the both sides, 
m - 7 + 7 < 6 + 7
m < 13
So, Option C is your answer for this part.
2) x+4.5 ≥ 5.5
Subtract 4.5 from both sides, 
 x ≥ 1
So, Option B is your answer for this part.
3) p +12 > 9
Subtract 12 from the both sides, 
p > -3
So, Option D is your answer for this part.
4) x - 5 ≥ 9
So, Option A is your answer for this part
Hope this helps!
