To make a scatter plot in Python, which matplotlib command(s) we can use?

Select one:

b. plot() only

c. both plot() and scatter(), but plot() provides greater flecibility

d. scatter() only

e. both plot() and scatter(), but scatter() provides greater flecibility

What command would you issue to insert legend at the lower left of the plot? Assume you have already issued the following commands and that x and y are both defined:

Select one:

a. ax.legend(loc = 'lower left')

b. fig.legend(loc = 'lower left')

c. ax.legend(location = 'lower left')

d. legen(loc='lower left')

e. figure.legend(location = 'lower left')
