[R] Linear model with one known coordinate

[abaresic]

Dear All,
I have a question which seems trivial, but I reached a dead end.
I have a set of points (measurements) and I used lm() to obtain their linear
regression model. From the biological background this line must pass through
a point (100,0). Our dataset is not optimal and it shows a slight deviation
from that coordinate. How can I add the restraint to the model, to go
through that point?

Any help would be appreciated.
