Multiple line subplots in R

I am new to R and am struggling to understand how to create a matrix line plot (or plot with line subplots) given a data set with let's say one x and 5 y-columns such that: -the first subplot is a plot of variables 1 and 2 (function of x) -the second subplot variables 1 and 3 and so on The idea is to use one of the variables (in this example number 1) as a reference and pair it with the rest so that they can be easily compared.

Thank you very much for your help.

Here's an example of one way to do that using tidyr and ggplot. tidyr::gather can pull the non-mpg columns into long format, each matched with its respective mpg. Then the data is mapped in ggplot so that x is mpg and y is the other value, and the name of the column it came from is mapped to facets.

library(tidyverse)
mtcars %>%
  select(rowname, mpg, cyl, disp, hp) %>%
  gather(stat, value, cyl:hp) %>%
  ggplot(aes(mpg, value)) +
  geom_point() + 
  facet_grid(stat~., scales = "free")

enter image description here
