For the direct variation equation y=38x, what is the constant of proportionality
The constant of proportionality in the direct variation equation y = 38x is 38.
The constant of proportionality in a direct variation equation represents the relationship between the variables. In the equation, y=38x, the constant of proportionality is the coefficient of x, which is 38. Therefore, the constant of proportionality in this equation is 38.
To find the constant of proportionality in a direct variation equation, we need to look at the coefficient that accompanies the x variable.
In the given equation y = 38x, the coefficient of x is 38. This means that for every one unit increase in x, y will increase by 38 units. Therefore, the constant of proportionality is 38.
