Directly Proportional


The equations of such relationships are always in the form Y = m•X, and when graphed produce a line that passes through the origin.  In this equation, “m” is the slope of the line   (or coefficient of proportionality, unit rate, rate of change).


Proportions can be used when converting between units of measure


  1. Set up your proportion.
  2. Multiply means and extremes
  3. Solve for “x” algebraically.
