A linear relationship
it is a proportional relationship because a proportional relationship is known as a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
A ratio shows the relationship between two quantities.Formula

It is a direct proportion.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
Direct variation.
A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
A math expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
the differentiate between fundamental quantity and derived quantity?
A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.
The relations between quantities are stated by multiplicative relationship between the quantities.
