I have a pooled result from multiple datasets with:
intercept = 22.35
slope = -1.23
Or alternatively, Y = 22.35 - 1.23*X1
How can I create a regression line in R based on this information?

2By "create a regression line" do you mean "plot this line"? – Gregor Thomas Apr 09 '21 at 13:54

2In base R, `curve(22.35 - 1.23 * x, from = -2, to = 10)`. See the dupe for other options – Gregor Thomas Apr 09 '21 at 13:58

2If you have an existing base plot, you can use `abline` to add a line, `abline(intercept, slope)`. If you are using `ggplot`, you can use `geom_abline`. – Gregor Thomas Apr 09 '21 at 14:00
