The answer is explained below

Step-by-step explanation:

y = kx

A) y is directly proportional to x

When two terms are directly proportional to each other, it means that as one term increases, the other term also increases. Also as one term decreases, the other term also decreases.

If y is directly proportional to x, and k is the constant it can be represented by the equation:

y = kx

y = k/x

C) y is inversely proportional to x

When two terms are inversely proportional to each other, it means that as one term increases, the other term also decreases. Also as one term decreases, the other term increases.

If y is inversely proportional to x, and k is the constant it can be represented by the equation:

y = k/x
