I have a 2 different datasets. I plotted two of their regreesion lines. I need to show these two in the same regression plot. How can I do?

You can create an "empty" plot with type="n" and then add your regression lines with abline

df <- mtcars

reg1 <- lm(mpg~cyl,mtcars)
reg2 <-lm(disp~hp,mtcars)
plot(c(0,0),c(0,60),type="n")        
abline(reg1)
abline(reg2)

you also can add points with points if you want. Then you also don't need to make the empty plot before, since it's "normal" plotting and then just adding ablines.
