How do you determine whether #5x-y=0# is an inverse or direct variation?
To determine whether the equation 5x-y=0 represents an inverse or direct variation, we need to examine the coefficients of x and y. In a direct variation, the equation takes the form y = kx, where k is a non-zero constant. In an inverse variation, the equation takes the form xy = k, where k is a non-zero constant.
In the given equation 5x-y=0, we can rearrange it to y = 5x. Since the equation is in the form y = kx, where k=5, it represents a direct variation.

Direct variation.
This is a direct variation , as y increases , x increases.
In inverse variation , as y increases , x decreases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
