Negatively Proportional

Introduction:

Two quantities are said to be negatively proportional if they vary in such a way that one of the quantities is a constant variable of the other, or equivalently if they have a constant ratio. Sometimes two proportional variables are said to be directly proportional. This is completed so as to contrast direct proportionality with negative proportionality.

Two variables are negatively proportional if one of the variables is directly proportional with the multiplicative negative of the other, or equivalently if their product is a constant. It follows that the variable y is negatively proportional to the variable x if there exists a non-zero constant k such that

Y= k/x

K is a constant above which could be found using x and y variables.

The negative proportions says that absolute value of one variable is bigger and another variable is smaller but their product of two variables remain the same.

For Example:

The time taken by the bus is negatively proportional to the speed of busl; the time take for cutting a tree is negatively proportional to speed of cutting a tree.

Let us take a graph that as two variables varying negatively. The resulting product of the X variable and Y variable values of all the point on the curve will equal the constant of negative proportionality (k). Negatively proportional k be never equal zero, the graph will never cross x and y axis.
