Points of a line, (n,C(n)).
Given or described points are (90, 37) and (252, 52).
Find the function as C%28n%29=m%2An%2Bb.

A possible calculation,
C%28n%29-37=%28%2852-37%29%2F%28252-90%29%29%28n-90%29

For one flyer:
+C%28n%29+=+%2837%2F90%29%2An+%2B+b+
For the other flyer:
+C%28n%29+=+%2852%2F252%29%2An+%2B+b+
+b+ is the fixed setup charge
