Inverse variation is a type of relationship between two variables where one variable increases while the other decreases, or vice versa. This means that as one variable changes, the other changes in the opposite direction.
Direct variation is a type of relationship between two variables where one variable increases or decreases at a constant rate while the other variable also increases or decreases at a proportional rate. This means that as one variable changes, the other changes in the same direction.
A relationship is inverse if one variable increases while the other decreases. A relationship is direct if both variables increase or decrease at a constant rate. To identify the type of relationship, you can plot the data on a graph and see if the points form a straight line or a curved line.
The main difference between inverse and direct variation is the direction of change between the two variables. In inverse variation, one variable increases while the other decreases, while in direct variation, both variables change in the same direction.
Yes, a relationship can be neither inverse nor direct. This means that there is no clear pattern or trend between the two variables, and their changes are not related to each other. In this case, the variables are said to have no correlation or a weak correlation.
