I have a colormap (fig file) and I draw a line by hand. I want to get the equation of this line (slope and intercept). How?

If you drew the line with IMLINE, you use its handle, h, to get the endpoints
endpoints=getPosition(h);
From the endpoints of the line, you can compute the slope and intercept using elementary geometry.
