scoring Nomogram, that I need to create a formula, so I can calculate the score

[cchilds]

I have this scoring Nomogram, that I need to create a formula, so I can calculate the score via a program and using in line math like x=1/2*(3+1)

Here is the table. Is there a way to calculate the result on the right, given the number on the left?

This looks to me like a perfect occasion to make use of a line of best fit. What result do you get if you try that? If you're unfamiliar with the concept, or need a refresher, try this page.
