Interpolation Equation

[Johnh]

That simple use of linear regression with two points is really useful! Actually it may be more useful in day-to-day engineering than the more common use of LR with multiple points. Thanks! And it's so simple that there's no point in making a dedicated program.

Today's example for me in structural design: Design standards give us wind pressure coefficients at various building heights. To get the values at intermediate heights, we interpolate from the nearest values above and below.
