To plot a horizontal line using matplotlib in Python, we can use the axhline method.
For instance, we write
import matplotlib.pyplot as plt
plt.axhline(y=0.5, color='r', linestyle='-')
plt.show()
to call axhline with the y value for the horizontal line.
And we set the color and linestyle for the line.
Then we call show to show the line.
The line y = 0.5 is then plotted.
