The gas used and miles are proportional for each scooter.
<h3>What is proportional relationship?</h3>
Proportional relationships are relationships between two variables where their ratios are equivalent.
A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y = k x
for some constant k , called the constant of proportionality .
Therefore, let's check whether the scooter A and scooter B shows proportional relationships.
Hence,
For scooter A:
y = kx
where
- x = miles covered
- y = gas used
Therefore,
2 = 150 k
k = 2 /150
k = 1 / 75
Hence,
y = 1 / 75 x
From the table of scooter A, the ratio is constant, therefore, the relationships of gas used and distance covered is proportional for scooter A.
For the Scooter B the graph is also proportional because the ratios of the variables are constant.
