It is a mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other. It occurs whenever a situation produces a pair of numbers in which the ratio is constant.
How is direct variation translated mathematically?
In the relationship y = kx, what is the independent variable?
It is a mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant. It occurs whenever a situation produces a pair of numbers whose product is constant.
How is inverse variation translated mathematically?
What type of variation where the situation produces a pair of numbers whose product is constant?
A direct variation is a situation that produces pairs of numbers whose ______ is constant.
If y varies directly as x and y = 30 when x = 5, find the constant of variation.
If y varies inversely as x and y = 6 when x = 12, find the constant of variation.
