A relationship in which the ratio of two variables is constant is known as a direct variation or direct proportionality. In this relationship, as one variable increases or decreases, the other variable changes in a consistent manner, maintaining the same ratio. Mathematically, it can be expressed as ( y = kx ), where ( k ) is the constant ratio. This type of relationship is often seen in scenarios involving linear equations and proportional relationships.
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
It is the constant of proportionality.
A relationship is proportional if it maintains a constant ratio between two variables. This can be determined by plotting the data on a graph; if the points form a straight line that passes through the origin (0,0), the relationship is proportional. Additionally, you can check if the ratio of the two variables remains the same for all pairs of corresponding values. If the ratio changes, the relationship is not proportional.

The constant of proportionality between two variables is the ratio of one to the other.
Inversely proportional.
Direct proportionality. Their graph would be a straight line through the origin, with the slope equal to the ratio.
It is the constant of proportionality or the conversion factor.
