To find the constant of variation in a direct variation equation, you divide one variable by the other when both variables are known. In this case, you divide y by x: (-10)/2 = -5. So, the constant of variation is -5.
Then, to write the equation of direct variation, you use the formula y = kx, where k is the constant of variation. Substituting the value of k, we get y = -5x.

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.
