Standard form


Point Slope Form

Direct Variation

an equation in the form of y=kx and where k is a non-zero constant

Inverse Variation

k (in terms of direct variation)

- called constant of variation
- called constant of proportionality

k (in terms of inverse variation)

called constant of variation
