You cannot represent a proportional relationship using an equation.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.

Proportional is when it is proportional.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
You cannot represent a proportional relationship using an equation.
It is true in the case of inversely proportional relationship.
A proportional relationship exists when two variables are related by a constant ratio. In the expression y-2.5x, there is no constant multiplier connecting y and x, indicating a non-proportional relationship. If the relationship were proportional, the expression would be in the form y = kx, where k is a constant.
If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
they are equivalent
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.
Do all linear graphs have proportional relationship
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
Some are, some are not.
