Proportional is when it is proportional.
The relationship Y = kx is proportional, where Y is directly proportional to x with a constant of proportionality k. This means that as x increases, Y also increases in a linear fashion. In a nonproportional relationship, the ratio of Y to x would not be constant, and the relationship could be more complex, such as quadratic or exponential.
The answer is proportional.
Any relationship in which at least one pair of measurements has a different ratio to that for other pairs. Equivalently, it is a relationship in which all the points cannot be plotted as a straight line through the origin.
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.
It is a relationship which is non-linear. The same amount of change in the independent variable brings about different amounts of changes in the dependent variable and these differences depend on the initial values of the independent variable.
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 graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.

Non-proportional vectors are vectors that do not have a constant scalar multiple relationship between them. In other words, they do not lie on the same line or in the same direction. Non-proportional vectors are linearly independent and have different magnitudes and directions.
