Inverse Variation Calculator

Solve inverse variation problems: y = k/x

x value

y value

Basic Formula

y = k/x or xy = k

k is the constant of variation

Finding k

k = xy

Multiply x and y values

Finding y

y = k/x

Divide k by x value

Finding x

x = k/y

Divide k by y value

Physics

• Pressure and volume

• Speed and time

• Force and distance

Economics

• Supply and demand

• Price and quantity

• Workers and time

Engineering

• Gear ratios

• Resistance and current

• Intensity and distance

• As x increases, y decreases proportionally

• The product xy is always constant (k)

• Graph is a hyperbola

• Opposite of direct variation
