Two variables are proportional to one another if there is a simple relationship, of the following form:
The variables X and Y are in
direct proportion if Y = c*X
and
inverse proportion if Y = d/X or, equivalently, X*Y = d
for some non-zero constants c and d, called the constants of proportionality.
Note that if Y is inversely proportional to X, then Y is directly proportional to the variable 1/X
The graph of a direct proportion is a straight line through the origin, with slope = constant of proportionality.
A math expression is a collection of math terms
In math, proportional means that two quantities always have the same relative size. For example, the lengths of these two shapes are proportional (one shape's length is always twice as large as the other.)
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
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.

A mapping is a relationship between two sets.
Proportional is when it is proportional.
When two amounts are matching when one or the other of each the two amounts increases or decreases.
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.
It is true in the case of inversely proportional relationship.
You cannot represent a proportional relationship using an equation.
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.
The relationship between mass and speed in terms of their physical interaction is described by Newton's second law of motion. This law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. In simpler terms, an object with a larger mass requires more force to accelerate to a certain speed compared to an object with a smaller mass.
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.
