Find 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.
In the equation y = 38x, the constant of proportionality is the coefficient in front of the x term. Therefore, the constant of proportionality in this equation is 38.
To find the constant of proportionality in a direct variation equation, you need to understand that a direct variation equation is written in the form y = kx, where k represents the constant of proportionality.
In the given equation, y = 38x, we can see that the constant of proportionality is 38. Therefore, the constant of proportionality is 38.
To understand how this works, you can observe that the value of y is directly proportional to the value of x. This means that if you increase x by a certain amount, y will also increase by the same multiple of that amount. In this case, for every one unit increase in x, y will increase by 38 units, making 38 the constant of proportionality.
