Proportions

Proportions

1. Direct Proportions

   • a relationship in which the ratio of two variables is constant
   • the density of water
   • Ohm's Law
   • weight = mass*gravity
   • Directly proportional graph
     • Directly proportional graphs are linear.
   • when the independent variable increases, so does the responding variable

2. Inverse Proportions

   • a relationship in which the product of two variables is constant
   • how the flow rate of a water faucet affects the time required to fill a pot
   • when the independent variable increases, the responding variable decreases
   • Inversely proportional graph
     • Inversely proportional graphs are non-linear
