Question

What kind of a variation does the function $y=\frac{8}{x}$ represent?

• A. Direct Variation
• B. Indirect Variation

Answer 1

The correct option is B Indirect Variation

The given equation:

$y=\frac{8}{x}$

$\Rightarrow yx=8$

Which means $yx$ = constant ($k$), which is the formula for indirect variation as opposed to direct variation whose equation is $y=k\times x$.

Option (b.) is correct.
