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.

To draw a graph of \(y = mx + c\) for given values of \(x\): Use the pairs of values in the table to list the coordinates ... the value on the \(x\)-axis. A linear graph could be used when ...

For example, in the right hand graph ... a linear approximation (e.g., the straight line drawn through the data points in Figure 5). If we presume the r of the exponential equation is a function ...
