a constant ratio of two variables related proportionally. Expressed with the variable k. | constant of proportionality |
the constant, k in direct and inverse variation equations. | constant of variation |
a linear relationship between two variables, x and y, that can be written in the form y=kx, where k is a nonzero constant. | direct variation |
a relationship between two quantities in which the ratio of one quantity to the other quantity is constant. | proportional relationship |
