To write the direct variation equation, you need to find the constant of variation (k) by using the given values of x and y. Once you have k, you can use it to find y for a different value of x.

Given y = 4 when x = 16, you can find k as follows:

y = kx 4 = k(16) 4 = 16k k = 4/16 k = 1/4

So, the direct variation equation is y = (1/4)x.

To find y when x = 6, plug x = 6 into the equation:

y = (1/4)(6) y = 6/4 y = 1.5

Therefore, when x = 6, y = 1.5.

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.
