For the direct variation equation y=38x , what is the constant of proportionality?
The constant of proportionality in the equation y=38x is 38.
To find the constant of proportionality in a direct variation equation, you need to compare the ratio of the two variables. In this case, the direct variation equation is y = 38x.
Let's break it down:
- The variable "y" represents the dependent variable.
- The variable "x" represents the independent variable.
- The number 38 represents the constant of proportionality.
In a direct variation equation, the constant of proportionality is the coefficient of the independent variable. In this case, the coefficient of "x" is 38. Therefore, the constant of proportionality in the given equation is 38.
