Question

What is the direct variation?

What is inverse variationion?

Answer 1

Answer:

1) Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if: y=kx. for some constant k , called the constant of variation or constant of proportionality

2) While direct variation describes a linear relationship between two variables , inverse variation describes another kind of relationship. For two quantities with inverse variation, as one quantity increases, the other quantity decreases.

Answer 2

Answer:

1) Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if: y=kx. for some constant k , called the constant of variation or constant of proportionality

2) 1 : mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
