Help with calibration

Using y=mx+b
If I have experimental sample data that's 500 ppm Sn
And using the instrument on the standard sample that was given to me was 34 ppm how can I apply this correction to the experimental 500 ppm?

Thanks

If anyone knows a function in Excel that does this I would b extremely helpful

I have a few values I need to form into an equation that I can apply to 3000 other values individually
1. certified concentration from standards; for example Zr (560 ppm)
2. personally measured concentration of standard; for example Zr (378 ppm)
3. Experimental measurement of Sample; For example Zr (62.605 ppm)

so I subtracted 1 from 2 to get the change in ppm (+182 ppm)

Now I need to apply and correct 1000 Experimental samples with the +182 ppm using the slope formula
