## Section 0.4 Solving Equations

ΒΆ*graphically*determine the solutions to that pair of linear equations. Moreover, we can determine solutions to general systems of equations either

*with a graph*, or

*by substitution*, or

*by elimination*, or with any combination thereof. Surpisingly, exponential curves have much in common with lines, so we'll consider curve fitting as a particular application. (I also wouldn't be doing my job if we didn't review exponential functions.)
