Interpolation formula

Hi there,

if I plot a graph with Excel, I can make it do an interpolation, and the graph also shows it's equation: there is a way to calculate that equation starting from the points?

In the attached example, what I'd like to have from the points, without having to plot the graph, it's the equation y = 0.0607x + 5.4587, so that I can input x values and get y's.

I'm using Excel 2007.
