I have this curve fit plot. as shown in the figure below. How can I find at y = 0? as marked in the figure. This is a point where y = 0. I need a generalized code which can keep on finding value at y = 0 and keeps storing in a table.

fitresult(1) is evaluating the model at x = 1, not extracting the first coefficient.
coeffs = coeffvalues(fitresult);
m = coeffs(1);
b = coeffs(2);
Yintercept = b;
Xintercept = -b/m;
