For the direct variation equation y=223x, what is the constant of proportionality?
in a direct variation of the form y = kx, k is the constant of proportionality.
So ....
To find the constant of proportionality in a direct variation equation, you need to match the equation with the general form of direct variation, which is y = kx.
In the given equation, y = 223x. Comparing this with the general form, you can see that the constant of proportionality is represented by the value of "k."
Therefore, in this case, the constant of proportionality is 223.
