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.
Proportional and non-proportional relationships both describe how two variables interact and change in relation to one another. In both types of relationships, changes in one variable can affect the other, and they can be represented graphically, typically with a line. However, while proportional relationships maintain a constant ratio between the variables, non-proportional relationships do not, leading to different patterns in their graphs. Both are essential for understanding mathematical concepts and real-world applications.
Do all linear graphs have proportional relationship
Proportional linear relationships have a constant ratio between the two variables and pass through the origin (0,0), meaning that if one variable is zero, the other is also zero. In contrast, non-proportional linear relationships do not have a constant ratio and do not necessarily pass through the origin; they include a y-intercept that is not zero, indicating a fixed value when the independent variable is zero. This results in different graphs, with proportional relationships forming straight lines through the origin and non-proportional relationships forming straight lines that intersect the y-axis at a point other than the origin.
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

For proportional relationships the ratio is a constant.

They aren't.
a proportional relationship means that it is contributed equally into other parts or quantities

y is inversely proportional to x if it is proportional to 1/x.
