Create a macro to carry out linear interpolation using the formula

$y=y_1+\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Use relative addressing. Give the macro a name, a shortcut key, and a description. This macro should be able to be used on various sets of values, at various locations on your worksheet, without changing the coding in the of the macro itself.

Try your macro out with the following set of data, solving for $x=2\mathrm{.}03$ :
