The formula for direct variation is y = k × x and the formula for inverse variation is y = k/x
The direct variation represented by the equation
y ∝ x
Its is y directly proportional to x
Where x is the independent variable
y is the dependent variable
By replacing the ∝ sign with the equal sign. The equation will be
y = kx
Where k is the constant of proportionality
Similarly the inverse variation is
y ∝ 1/x
Replace the ∝ sign with the equal sign
y = k/x
Therefore, the direction variation represented by y = k × x and inverse variation represented by y = k/x
