Answer:
Car B has the better fuel economy.
Step-by-step explanation:
Calculate the fuel consumption for the two cars:
Car A: (450 km) / (40.5 L) = 1.11 km per L
Car B: (220 km) / (18.7 L) = 1.18 km per L
Car B goes further on one L of gasoline than Car A.
The value of p = 11
y = 5x + p
1 = 5(-2) + p
1 = -10 + p
11 = p
I think the answer is B but not sure about "11" in A
