The easiest way to think about this is by example:
Direct Proportionality:
"A isproportionalto B"
That means A is equal to the product of B and some constant (usually denoted as k).
A = kB, where k is some constant
Simply put, if A goes up in value, than B goes up in value. If A goes down in value, B also goes down in value. They key here is A and B are either both in the numerator (top of a fraction) or the denominator (bottom).
(1/A) = k(1/B), where k is some constant
This time both A and B are in the denominator, but that's okay because they are BOTH in the denominator.
Inverse Proportionality:
"A is inversely proportional to B"
If A is in the numerator, B is in the denominator, and vice versa.
A = k(1/B)
(1/A) = kB
Simply put, if A goes up B goes down. If A goes down, B goes up.

How can you know if a graph represents a proportional relationship?
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.

What is the difference direct variation and inverse variation?
Direct variation is the ratio of two variable is constant. Inverse variation is when the product of two variable is constant. For example, direct variation is y = kx and indirect variation would be y = k/x .

Does a supply curve show a direct or inverse relationship between price and quantity supplied?
Yes, it does.
What are the different kinds of proportions and its examples?
There are several types of proportions, including direct, inverse, and joint proportions. Direct proportion occurs when two quantities increase or decrease together, such as speed and distance (e.g., doubling speed doubles the distance traveled in a fixed time). Inverse proportion exists when one quantity increases while the other decreases, like the relationship between speed and travel time (e.g., increasing speed reduces travel time). Joint proportion involves multiple variables, where a quantity is directly proportional to the product of two or more other quantities, such as the volume of a gas being directly proportional to its temperature and the number of moles.
