some people being ugly and weird just kidding I'm only a third grader how should I know
Some are, some are not.
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.
Mass measured in kilograms and in pounds. If you travel at a constant velocity, the time that you travel and the distance that you cover.
Non-proportional refers to a relationship or situation where two quantities do not maintain a constant ratio or relationship as one changes. In non-proportional relationships, as one variable increases or decreases, the other does not change in a consistent manner. This concept is often contrasted with proportional relationships, where a change in one quantity results in a predictable change in another. Examples can be found in various fields, such as mathematics, economics, and physics.

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.
Mass measured in kilograms and in pounds. If you travel at a constant velocity, the time that you travel and the distance that you cover.
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.

To determine if an answer represents a non-proportional relationship, check if the ratio between the two quantities remains constant. If the ratio changes as one quantity increases or decreases, or if the graph of the relationship does not pass through the origin, it indicates a non-proportional relationship. Additionally, if there is a fixed amount added or subtracted rather than multiplied or divided, the relationship is also non-proportional.
