Question

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.

Find the constant of variation when one exists and write it in simplest form.

Answer 1

For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .

For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .
