"indirectly proportional" appears to be interchangeable with "inversely proportional."When a dependent variable is inversely proportional to an independent variable, that means it decreases as the dependent one increases, and vice versa. For example, a baseball player's batting average is inversely proportional to the number of at-bats. (It's directly proportional to the number of hits he gets.) In other words, as the number of at-bats increases, the player's batting average decreases. Another example is gravitational attraction between two bodies. The gravitational force between two bodies is inversely proportional to the square of the distance between them.
Cross multiply then solve for the variable.
if one goes up as the other goes down (or vice versa) they are inversely proportional
Example of inverse proportion is: Density = Mass/Volume Because the formula represents that the density is directly proportional to the mass while density is inversely proportional to volume. Remember that inversely proportional means that if variable A increases, the variable B decreases, and if variable B increases, the variable A decreases.

In a directly proportional relationship, as one variable increases, the other variable also increases at a constant rate. In an inverse proportional relationship, as one variable increases, the other variable decreases at a constant rate.
Words such as "proportional to" "increases as" "decreases as", usually give an indication of a linear relation. If there are words like "Square" "power" "inversely proportional" then most likely not linear.

if one goes up as the other goes down (or vice versa) they are inversely proportional
Two variables are directly proportional to each other if they increase or decrease together at a constant rate. In other words, if you plot the relationship between the two variables on a graph and the points lie on a straight line passing through the origin, then they are directly proportional. Mathematically, this can be expressed as y = kx, where k is a constant.
Example of inverse proportion is: Density = Mass/Volume Because the formula represents that the density is directly proportional to the mass while density is inversely proportional to volume. Remember that inversely proportional means that if variable A increases, the variable B decreases, and if variable B increases, the variable A decreases.
The variable that is directly proportional to frequency is the pitch of a sound wave. This means that as frequency increases, pitch also increases.

Depends on the experiment - there may be no relationship. Typically proportional, inversly proportional, proportional to the log and similar are given in set experiments at schools. So a staight line going up and straingt line going down or a curve of some sort when drawn as a line graph.
When two variables are directly proportional, it means that as one variable increases, the other variable also increases at a constant rate. In mathematical terms, this relationship can be expressed as y = kx, where y is one variable, x is the other variable, and k is a constant value.
