This article discusses the practical application of exponent rules and how they relate to business and finance scenarios.

A common use of exponents in business and personal finance is the investment of money at a fixed rate for a variable period of time.  For example, let's say we have $10,000 we want to invest.  A CD yields a 6% annual rate, so we decide we want to invest it for 20 years since.  What will be it's value when the CD matures?

Below are some example graphs of common equations and inequalities that you are likely to encounter.  

The method you use to draw your graph depends on the form of your equation.

slope intercept form:  y = mx + b

standard form:  Ax + By = C

For slope intercept form (y = mx + b) set your x = 0 and by default your y will be equal to b.  This will be your starting point.  From there you can use your slope to plot the next point.  Slope is equal to rise/run or y/x, so you would go up y places on the graph and across x places.  Draw a straight line between your two points.
