Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend.

At the point (or points) where two graphs intersect, the \(x\) and \(y\) values are the same for both functions. We use this information to find the solution to simultaneous linear equations.

Unlike a linear, graph, ... Graphs of quadratic functions can be used to solve equations. Example. Draw the graph of \(y = 2x^{2} + 2x – 4\) for values of –3 to 2.
