How do I find the slope and intercept of two-points in Labview

[Robert W]

This should be quite easy to do, But how do I have a user enter two (x,y) points and have labview give them the slope and intercept?

Thanks

On the Mathematics>Fitting palette is Linear Fit. You provide an x array and a y array and it returns the slope and intercept.

I realize that, but how do I put just two x values and two y values into an array to use the lienar fit vi.

Thanks and Regards

How about just two sets of X Y value pairs?




Darn, I'm too slow.

One way is to simply use the Build Array function.
