Made a little change to your code at number 9

[Stephenob6]

Set the figure style and initalize a new figure

plt.style.use('fivethirtyeight')
fig = plt.figure(figsize=(12,8))

Create a scatter plot of duration versus release_year

plt.scatter(netflix_movies_col_subset["release_year"], netflix_movies_col_subset["duration"], c = colors)

Create a title and axis labels

plt.title("Movie duration by year of release")
plt.xlabel("Release year")
plt.ylabel("Duration (min)")

Show the plot

plt.show()
