Is the equation #y=x-2# a direct variation? If it is, how do you find the constant of variation?

Answer 1

#y = x-2# is not a direct variation.

A direct variation means that #y# is proportional to #x#. In other words, they are equations of the form #y = kx# where #k# is a constant value.

#y = x-2# is not of the form #y=kx#, so it is not a direct variation.

No, the equation y = x - 2 is not a direct variation.

In a direct variation, the equation takes the form y = kx, where k is the constant of variation.

To find the constant of variation in a direct variation equation, divide y by x. In this case, y = x - 2, so the constant of variation cannot be determined because the equation is not in the form of y = kx. Therefore, there is no constant of variation for this equation.

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.
