Proportional relationships refer to a consistent, direct relationship between two quantities, where one quantity is a constant multiple of the other. This means that as one quantity increases or decreases, the other does so at a constant rate, maintaining a fixed ratio. In graphical terms, proportional relationships are represented by straight lines that pass through the origin (0,0). An example is the relationship between distance and time at a constant speed.
Direct variation.
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
The relationship between two quantities that increase together is called a positive correlation. In this scenario, as one quantity rises, the other quantity also tends to rise, indicating a direct relationship between the two. This can often be represented graphically with an upward-sloping line on a scatter plot.
A math expression is a symbol or combination of symbols that represents a quantity or a relationship between quantities.
A linear relationship
It is called direct variation.
it is a proportional relationship because a proportional relationship is known as a relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
The proportionality constant in physics is important because it defines the relationship between different physical quantities in an equation. It determines how one quantity changes in relation to another. For example, in Newton's second law of motion, the proportionality constant relates force to acceleration. Changing the value of the proportionality constant can alter the strength of the relationship between the quantities being studied.
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
It is a direct proportion.
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).

Direct variation.
A proportional relationship between two quantities is one in which the two quantities called the unit rate, the rate of change, or the constant of proportionality.
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
