  1. Load the cars dataset and select observations with a reported speed of less than 20kph. Plot speed vs distance on scatter plot
cars <- cars %>% filter(speed<20)
as.tibble(cars)

plot(cars)

  1. Now select only the speed variable from the cars dataset and plot this on a scatter, where x axis defaults to index
speed <- cars$speed
plot(speed)

3. Repeat for the distance variable from the cars dataset

dist <- cars$dist
plot(dist)
