Direct variation
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
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.
It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.
A relationship between two quantities where the rate of change or the ratio of one quantity to the other is constant is known as a direct proportion. In this scenario, as one quantity increases or decreases, the other quantity changes at a consistent rate, maintaining a fixed ratio. For example, if you have a constant speed while traveling, the distance covered is directly proportional to the time spent traveling. This relationship can be expressed mathematically as ( y = kx ), where ( k ) is the constant of proportionality.
To determine if there is a proportional relationship between two quantities using a table, you can check if the ratio of the two quantities remains constant across all entries. Specifically, divide each value of one quantity by the corresponding value of the other quantity for each row; if all ratios are the same, the relationship is proportional. Additionally, the table should show that when one quantity is multiplied by a constant, the other quantity increases by the same factor. If these conditions are met, the two quantities are proportional.
Direct variation
A linear relationship
In that case, one quantity (the quantity that depends on the other) is said to be a function of the other quantity.
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.
It is called direct variation.
Rocky best describes the relationship between Slytherin and the other founders - but the other three were friends.

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.
This is known as an inverse relationship or a negative correlation. It means that as one quantity goes up, the other goes down, and vice versa.
Boyle's law describes the fact that, at constant temperature, the pressure and volume of a particular sample of gas are inversely proportional. As one quantity increases, the other decreases, and vica versa.
Current is considered a base quantity because it is a fundamental physical quantity that cannot be defined in terms of other physical quantities. It describes the rate of flow of electric charge in a circuit and is measured in units of amperes (A). Charge, on the other hand, is a derived quantity that depends on current and time, making current the more fundamental quantity.
