Directly proportional relationships mean that if one of the related things is multiplied in size by a number, which we'll call x, then the other related thing is also multiplied by x.
Inversely proportional relationships mean that if one of the related things is multiplied in size by a number, x, then the other related thing is divided by x (or multiplied by 1/x , the two are equivalent as multiplication and division are commutative, if that's of interest....)
Things can also be related by higher order proportionality. If thing P is proportional to the square of Q (a proportionality of order 2) then if Q is multiplied by a number x, P is multiplied by x2.
In general though, if two things are in a proportional relationship it means that when one is multiplied by a certain amount, the other is multiplied by a related amount.
Either a straight line through the origin or a hyperbola.
Do all linear graphs have proportional relationship
rational number
Here is a quick definition: un-proportional is where two things cannot ever be equal or similar, for example 2 is proportional to 4, because if 2 is doubled it becomes 4, but 3 is not proportional to 5 because they can never be equal. I hope this helped
Corresponding in size or amount to something else.

For proportional relationships the ratio is a constant.
Do all linear graphs have proportional relationship
They aren't.
a proportional relationship means that it is contributed equally into other parts or quantities
