Proportional Relationships on the Coordinate Plane

A _______ is a relationship in which the ratio of one quantity to the other quantity is equal

A proportional relationship is a ________ that passes through the origin (0, 0)

Proportional relationships can be expressed as

• k = y divded by x

• k = y/x

• y =mx + B

• y = kx
