Inverse Variation (VCE SSCE General Mathematics): Flashcards

One variable increases as other decreases

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

$y \propto \frac{1}{x}$

Constant of variation

$xy = k$ (constant)

Hyperbola (curved shape)

Straight line

Check if $xy$ is constant for all data pairs

As $x$ increases, $y$ decreases
