How do I extract just the number from a named number (without the name)?

I am looking for just the value of the B1(newx) linear model coefficient, not the name. I just want the 0.5 value. I do not want the name "newx".

newx <- c(0.5,1.5,2.5)

newy <- c(2,3,4)

out <- lm(newy ~ newx)

out looks like:

Call:
lm(formula = newy ~ newx)

Coefficients:
(Intercept)         newx  
       1.5         1.0  

I arrived here. But now I am stuck.

out$coefficients["newx"]

newx 
 
1.0
