Lines are so important that they deserve their own section in the book of Math. The linear graph is More line calculators Graph the following equations: \(\frac\). In Calculus and Optimization, so they are Linear functions appear in applications all the time, Lines or linear graphs are truly present everywhere. Similar to what happened with addition and subtraction, dividing fractions is just derived from the multiplication of fractions: To divide two fractions, you just multiplyįirst one by the inverse fraction of the second one (the inverse fraction is obtained by swapping the numerator by the denominator in the fraction). Using that method, when the lines are parallel and don't intersect, there will not be any solutions. For example, you can solve a system of equations by graphing theĬorresponding lines and seeing where they intersect. Lines are super easy to draw, just you need to be methodical and be aware of the type of information you have available.Įven if you do it by hand, it is always nice to have a handy linear graphing calculator online to check your results.
