It is the constant of proportionality.
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
For a direct variation equation the constant MUST be 0. Then the ratio of a pair of values of the two variables is the slope.
The two types of variables are the CONSTANT and CONTROL.
It is simply a ratio between two variables. There is no information on what measures the letters represent, nor whether the ratio is a constant or variable (eg between Celsius and Fahrenheit).
It is the constant of proportionality.
It is the constant of proportionality.
The constant of proportionality between two variables is the ratio of one to the other.
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
It is the constant of proportionality or the conversion factor.
It is a direct proportion.
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
Quotient.
dependent
Two variables related in such a way that their values always have a constant ratio directly vary.
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
If two variables are directly proportional to one another then the constant of proportionality is the ratio of their values. If they are in inverse proportion then the constant of proportionality is the product of their values.
